Only thing I remember was that the MC got sent into the bl story after winning the lottery and he's trynna set the ML to this girl however everyone misunderstood his actions and now they think they're boyfriends or sumthin. There's this white haired 2nd male lead i believe that is from another school and his mom is trynna hire a tutor and guess what and who the tutor is??! Yes it's the MC. After mc went to the white hair there's this funny thing I remember because why tf his door has so many locks??!

I dunno if someone knows this but plss I've been finding this for the last 2weeks because I can't find it again, I had it on my old phone but it doesn't work anymore so yeah:> （/TДT)/
