i think it's actually a quite good.
but i don't like the senpai. if the senpai love tomoki from the first, why he didn't tell him properly? and then after getting married he just say suddenly. it makes me sick. -_- didn't he think about his pregnat wife (?)
and for atsuya he 'did' it to tomoki just for make tomoki 'noticed' for him. at least, atsuya almost give up on him, when he used get back with his brother, he knows it will be end.
but at the end tomoki rejected the senpai and back to atsuya.
why they aren't have the translation ? T.T
