Hidden -> Steals GF, cock-blocks and/or Dates others

Seme in -> sleeps around w/ s & a + steals gf

Uni friends, popular seme who finally has his love requited, then a stalker crazy girl tries to separate them. Forward & honest (not a coward nor tsundere) uke. Well I don't like any of this author's work, but the uke's personality is a breath of fresh air.

Nam's dire situation and more than useless ability: having to experience his long-time sonovabitch bully, Ma Sangtae, 's perverted-gay-porn-fantasies (actually, memories with all his masochistic sex friends) if he gets in a 5 meters radius of the guy!
