i was thinking the same thing as well !!!
whether he wasn't in love enough with Ko-chan or he's making use of Takeru !!
Someone can't change feeling so easily, especially toward his lover's younger bro !!
And how long was he supposed to wait to fall in love again it's been five years not 5 min,hrs or months but 5 years where he was repeatedly raped by his brother and it didn't say he was in love with him those 5years it just said he thought of him
i think that the problem on this manga is not the time ( years, moths or day), but the way that manga developed... the feeling of the young brother and Hiro was so fast... that I wondered what's going on?... (っ°Д °)っ
Ko chan and hiro are in love and then next thing we know its five years later, and Hiro gets together with Takuro so easily. i mean come on its the brother of his dead lover doesnt he feel any guilt? plus, if he was inlove with Kochan why would he spend all those years thinking of Takuro? .he seemed to fall in love way to easily. maybe if it was longer and the feelings grew over time then i would have believed it.
