Headcannon from a non writer
I have this headcannon which I wish could be turned into a fanfic but since I am not into writing stories (writing stories are much different from writing blogs)
Okay so here it is. The main ship in the fanfic will be Seven x MC and Rika x V (past relationship). The main characters would be Seven, MC, Vanderwood Saeran, Rika and V.
In that headcannon, Seven would be a really popular kpop idol (instead of being an ethical hacker) who is in love with MC (another kpop idol and/or actress) but keeps pushing her away (just like he does in his own route) because he knows that if he and MC would get into a relationship, it would result in many disasters:- MC and him getting death threats from their so called "fans", stalker fans (sasaengs) trying to harm them, Seven himself facing the risk of getting kicked out by his company and possibly getting blacklisted which would mean the end of his career. Saeran would be an agent from a popular media outlet like Dispatch who is trying every means to ruin his brother's image. Rika as his boss and V as someone who is in prison because Rika had falsely accused him of crimes and like in the canon, they both would formerly be a couple. Vanderwood will be Seven's manager. Ofcourse "Seven" will be his stage name.
As for the other characters....I did not think much about it but I imagined Seven to be a part of a popular kpop boy group where he is with Zen and Yoosung. Zen as the leader of the group who is often the victim of Seven's and Yoosung's mischiefs.
Seven and Yoosung would have a slightly complicated relationship, to public they would look like having the classic Tom and Jerry kind of relationship, constantly teasing and bickering with each other but in reality they are very close and after his manager Vanderwood, Yoosung would be the only guy with whom he shares his feelings.
