Ok, I think it was a week back, I read a synopsis for a drama, possibly japanese not sure, may or may not have released also not sure, but I forgot the name..

Twins (boy & girl) study in school, one of them (the girl i think) is bullied a lot. She is saved by a weird fellow. They befriend him as he doesn't care about their non-existent social status (pretty much this exact term was used in the synopsis I believe) but ... he's hiding or involved in something and trouble ensues? That's all I remember...
