BLs where they are both childhood friends and the uke is inlove with the seme but the seme already has someone else so the uke has no choice but to let go of his feelings for seme. Seme is incredibly oblivious of uke's feelings for him and subconsciously gets jealous whenever somebody tries to get close to uke. (≧∀≦)
