uke is mouthy, intense and awkward. in lovemaking however, he shows his dere side w/c looked really sexy since outside of bed he's never like that.
the first gap moe chara that I ever loved and the reason why this list exists
at first look, seme is intimidating with his height and fierce thug-like face everyone is afraid of him. but uke sees other side of him that nobody noticed.
at first look, megane guy looks like your normal geeky classmate... until provoked. ran also has one huge character gap moe with his tough delinquent looks and the sweet faces he's making on their lovemaking.
he got it all. looks, talent and height. everyone is enamoured with him. except, nobody knows that his fake stoicism is just a result of his fragility. he's actually shy and timid despite the popular guy aura.
ch.4: total character gap from inside and outside the ring attitude (he's a wrestler) bara
ch.7: that huge smiley-face uke looks creepier than the uke who's got fetish since he can be cruel then kind the next and you don't know what he's thinking with his smile frozen on his face
ch.1 and ch.5, page 28-41 funny character gap. and when he's so strung up, hot monkey sex occurs. nice focus ass shots too
seme
the pediatrician sensei is definitely gap moe ^o^ his face is too stern yet he actually had a warm character which does not match up.
uke
1-4: icy straightlaced salaryman becames a lewd kitten in bed
seme switches from raging bull to fluffy cuteness in a dizzying speed.
he dresses in a really flamboyand/flashy way so he totally looks like a devilish honey boy but
he's actually sincere, kind, great at housework and aggressive in bed (despite looking all cute)
seme is a stupid delinquent that fell inlove with an okama who had much baggage as the amount of effort he puts on his crossdressing. uke's loathes his actual self when he sheds off the flashy clothes
