Real life, good or bad

Cheating is bad. It is. But anyway this manga is so worth reading, besides very good art,but mc's emotions are wonderfully shown, his doubts and memories; he is hated by readers, but he is just an average man, with his past,with painful love that changed him...This manga should be read by older readers, youngsters can only say "I hate cheaters" and that's all, but...This is real life, you never know what happens, you have to face your own feelings and everybody gets hurt.
