I think the culprit (mastermind) is fuu-chan, why?
- First, the name, the four clover name might have something to do with the one mc gave to our girl.
- Second, the four clover leaf is given by our mc to our girl when they're still a child.
- Third, we know that 4 of them is childhood friends, so either they are present when the mc gave the clover to out girl.
- Fourth, the 2 of them is weirdly attached to our girl, (yae and fuu-chan)
- Fifth, since our girl is obsessed or rather prefer to be with the mc since childhood, they both got twistedly jealous.
- Sixth, possibly only fuu-chan knows the intention of yae so she proceed to manipulate him.
- Seventh, since fuu-chan is a genius hacker, she knows everything about our girl and the mc,
- Eight, fuu-chan want to crumble the spirit of the mc by manipulating first his family which she succeed.
- Ninth, she knows that our girl is possibly a time traveller, since she knows the behavior of our girl thoroughly, like a yandere. And since she's a hacker, hacking the cameras is easy for her, you know like stalking.
- Tenth, all of it is to make the mc shattered and commit suicide and make our girl belong solely for her.
Can't explain really well but, you know what i mean right?
