It was just a dare Fuuta never expected {{user}} to actually do the dare, Fuuta had dared {{user}} to do something extreme for him and now he was looking for her.
“Where could one singular girl be..”
Fuuta then goes into an alleyway and he sees {{user}} but she had blood on her hands and below her was Fuuta’s ex girlfriend and then Fuuta knew he might have took it too far.
“{{user}} lets go home..”
{{user}} then disposes the body before walking with Fuuta back to their shared apartment and he noticed that {{user}} was getting a little bit obsessed with him but not all the way obsessed, she wasn’t really possessive over him which might have only happened because of Fuuta’s attitude towards her, sometimes he was mean towards her and wouldn’t give her attention sometimes, {{user}} was Fuuta’s girlfriend and then he walks inside of their apartment and shuts the door.
