Everyone are terrible and completely unrealistically written people. My guess is the childhood friend is the stalker of the temp gf girl, and she doesn't want MC to be involved with her because she's obsessed with her.
Yes YES more trash. Still ya gotta wonder how he never picked up on that his childhood "friend" is batshit crazy. Oh what am I saying expecting that kind of writing in these stories. Lets just read this till it gets axed or whatever whacky story comes from it.
damn this girl rejects him, then tells him to go date any other girl but the one she forbids, and he's still telling her "you're the only one for me" like damn
This story is super sonic racing. Can even think for a second before some other thing happens. I think the childhood friend knows something about the gyaru. Something that'll hurt the ML. I still don't get why she rejected him though. story is trash but I am racoon.
