|— Cheryl whispering to Archie in class[src]|
The relationship between Archie Andrews and Cheryl Blossom pre-dates the series. Even though not a lot of people like Cheryl, Archie never showed her a bad face. He was there for her when she needed him the most, especially when it came to being around her family, and in turn she helped him with his music by talking Josie into giving him a hand, and gave him a brand new electric guitar. Furthermore, Archie broke his wrist breaking the ice to save Cheryl from a suicide attempt. In return for saving her life, Cheryl offered to help Archie recover from his father being shot.
Even though they both go to the same school and share some of their classes, they never really interacted until recently, following the murder of Cheryl's twin brother, Jason. While the two can be called 'friends', Cheryl has tried to flirt with him on several occasions, but as Archie doesn't have that kind of interest in her, he quickly shut her down and changed the subject.
After Cheryl tried to commit suicide by drowning herself at Sweetwater River, Archie saved Cheryl's life by breaking his wrist to get through the ice and performing a CPR on her.
Kiss of Life
After the shooting of Fred Andrews at Pop's Chock'lit Shoppeby a hooded assailant, he was admitted into Riverdale General Hospital. Archie went back to his father's room to find Cheryl over his bedside, giving him a kiss on his forehead. Cheryl explained that she was repaying Archie for saving her life at Sweetwater River. He gave her the kiss of life, as she's now giving to his father. Cheryl then assured him that his father was going to be just fine, before leaving the room.
With the Black Hood terrorizing the town, Cheryl decided to join Archie in his crusade to protect the streets with a community group watched that he had formed and named the Red Circle. While she didn't join him in the streets she helped Veronica promote the Circle with T-shirts.
They didn't interact much, but Archie and Cheryl both attended Nick St. Clair's party at the Five Seasons. At the party was also, Betty, Reggie, Kevin, Josie, Valerie, and Melody. Cheryl told Archie to keep up as Nick told a story about his run-in with Gal Gadot. After a few drinks, Nick proposed they take the part one level further with some Jingle Jangle that he scored from Reggie. Without hesitation, Cheryl agreed to partake. She then looked to Kevin, asking if he would be joining, which he did. High off Jingle Jangle, Cheryl and Kevin danced on the couch together, though their drug-fueled dance off was short lived after an argument between Betty and Veronica erupted within the hotel room, which blew their high. After Betty accused Veronica of being a bad person and a friend of circumstances, she left the party.
Later that night, Archie rushed over to the Pembrooke after learning that Nick drugged and then subsequently tried to rape Cheryl at the SoDale Gala Opening. He asked where Nick was in that moment, though Cheryl told Archie that he could put his cape away because the Pussycats had already saved her.
Cheryl attended the drag race being held near Herk Harvey bridge between Archie and Jughead and two members of a Southside gang called the Ghoulies. Cheryl sat alongside Kevin, Reggie, Veronica, and Betty as the race was about to commence.
Archie and Cheryl were invited to Kevin's Secret Santa gift exchange in the student lounge at school, along with Betty, Reggie, Cheryl, Kevin, Veronica, Jughead and Josie. Veronica opened her gift from Josie, which awkwardly enough was a gift certificate for a couples massage. Archie and Veronica were still together when Josie purchase of the certificate. Hoping to lessen the awkward tension, Josie suggested that Veronica use the certificate to take someone other than Archie, such as Betty or her mother. If that wasn't able to be arranged, Reggie joked that he could use the gift certificate with Veronica's mother. Thankfully, as the awkwardness was too much to bear, Betty was the last exchange for the evening. Based on the wrapping of her present, she instantly knew that it was Archie who picked her name. Betty unwrapped the gift to find and old read-a-long record that she and Archie used to listen to when they were five years old, entitled "The Swiss Family Robinson". Archie informed her that he and his father found it while they were cleaning out the garage. Moose and Midge then entered the lounge to join them for the Holiday event.
Despite learning earlier that day that her family had no money, Cheryl headed down to Pop's Chock'lit Shoppe, where Archie and his father had set up shop for the selling of Christmas trees. She approached Archie and asked for their finest tree. Unfortunately, he was about to leave. So he pointed Cheryl into Vic's direction, who was assisting with the tree sales.
Under the suspicion that Nana Rose was present for the execution of the innocent man, Archie and Betty showed up at Thistlehouse uninvite. Cheryl answered the front door. She invited them in and took them to see Rose. Archie and Betty asked her about the execution of the Riverdale Reaper and if Nana Rose had accompanied the men when they killed him in the name of justice and revenge. Nana Rose revealed that she wasn't there to see the execution first hand as she was told to stay at home while the men took care of the killer. Where did they hang the Reaper, Betty asked. Rose replied that he wasn't hung. They gave him a proper burial by burying him alive. As for the location of the burial, Nana Rose, who mistook Betty for Polly, as she had done before, told Betty to ask her grandfather, who had shared in the execution. Rose had a picture of them at the burial, smiling just beneath the devil's hand, she remarked. Nana Rose then asked Cheryl to take her to her room as she had fell ill. 
After learning of the closing down of Southside High and the transfer of students to Riverdale High School, Cheryl, with Reggie, the River Vixens and the Riverdale Bulldogs in tow, interrupted Veronica's welcoming committee for the Southside transfers (Jughead, Toni, Sweet Pea and Fogarty). Cheryl approached the registration desk, hurling insults at the Serpents, calling them "Southside scum" and "raggamuffins". She refused to allow Riverdale High's above average GPA to suffer because of overcrowded classrooms with underachievers such as themselves. Cheryl told them to find another school to deface with their "hardscrabble ways". In saying this, she offended Toni, who dared Cheryl to say it to her face. Just as the two were about to face off, Archie stepped in between them, hoping to put their Northside and Southside differences aside to start over but the rivaling sides continued to go back and forth until Mr. Weatherbee arrived to send them off to class. However, before parting ways, Cheryl told Archie to reconsider his allegiance as she had witnessed the clandestine Christmas kiss between him and Betty outside of Thistlehouse.
In response to Cheryl's blackmailing, Archie texted her to meet him in the music room. Cheryl decided to keep it brief, proposing that Archie convince Veronica to stand with them against the Southside rabble or else she would tell Veronica about the kiss with Betty. Archie explained that Cheryl had nothing to tell considering that he and Veronica were broken up, as were Betty and Jughead. Nonetheless, that's not the reason why Archie messaged her. He wanted to talk about Nick St. Clair. He asked if Cheryl knew that he got into a bad car crash after he left Riverdale. Cheryl asked Archie to forgive her if she didn't shed a tear for the man that tried to rape her. She only wished that she and her mother hadn't burned the check that his family gave them as hush money. Cheryl concluded that Archie must've been thrilled after finding out about the accident given what Nick did to Veronica on the night of his party, when he got physical with her, which Archie had no knowledge of. He quickly grew angry, threatening to kill Nick. It was Veronica's right to tell Archie or not. Cheryl was sure there was a specific reason she kept it from him.
That night, Archie stopped by Thistlehouse as he couldn't stop thinking about what Nick did to Cheryl and Veronica. Archie asked if she wanted another check, to replace the last one that she and her mother had burned. She did. But Cheryl was afraid the ship had sailed on that. Archie would beg to differ. He planned on going to see Nick and he could ask him to write another check. Archie only needed from Cheryl to borrow one of Jason's blazers, to which she agreed.
The next day, after Archie had recovered the check from Nick and assaulted him in the process, Cheryl entered the music room at school to reveal to Veronica that she had unintentionally told Archie about Nick's sexual advances after the Five Seasons party and why Archie had gone to New York, behind her back. Cheryl claimed that it was a classic shakedown. She wanted money from Nick and she thought that Archie could convince him that reparations were in order. Her only regret was that she betrayed Veronica's confidence. Cheryl then issued an apology before walking out.

- Archie: "Forget them, Cheryl. Forget what they think. I think you're awesome."
- Cheryl: "Oh Archie. Sometimes I think you may be the only decent person left in Riverdale. The only person who doesn't want something from me or doesn't want me to apologize for who I am... Or what I want."
