Riley is not a fucking side quest. She is one of the two LIs the game gives you to choose from. She's literally half the story!
And what a story it is. Riley and MC are childhood friends who developed feelings for each other when they reached adolescence. MC was always too shy to confess to Riley, and was taking so long that she was about to take the initiative and confess to HIM when another dude asked her out. Riley was so impressed by his boldness that she accepted, and when you voiced no objection to her dating she decided that you must not have liked her after all, so she ended up giving her virginity away to some rando. She discovered that she really liked sex, so she became the town bike.
Now, years later, an older and wiser Riley realizes that you were in love with her back then, but unfortunately you have since gotten together with Mia. When Mia shows signs of straying, Riley realizes that this is her last chance to get together with you before you leave for college, and subtly enables Mia's cheating. At the same time, she begins cuckflirting with and training you, reconnecting with MC and laying the groundwork for her confession once you inevitably find out about Mia's betrayal.
If you play the Riley routes, it's clear as day that MC never got over her, and the story becomes about rediscovering your love for Riley. There is a very strong BSS vibe; the MC could have totally deflowered Riley if he had just manned up and confessed, but he didn't. Think "SF" or "My Beloved Childhood Friend Sleeps with Anyone".
