Years ago I read a shoujo with a rather simple art.

All I can recall is that there were 4 main characters: 2 childhood friends (I think? dark hair boy or so? The girl had short hair), then another school boy (white haired, playboy? maybe had a thing for the white hair girl) and finally there was this school girl (mature personality and was in love with this married teacher who led her on). Playboy-kun then start falling for mature girl and I'm dying to read how those two end up. I hope the series is complete now.

Thanks!

Maybe Kareshi Kanojo no Jijou or Sensei!

Thanks but it's not this one
