Nope. shiro is not a prostitue but the kiss part is somehow the same. they can have sex but never kiss unless it is someone they love. Please!! kiss already!! and please remove the woman!
I had fun reading this manga. It reminded me of super lovers, even the twins.. since in SL, shima and aki also act like it's normal for them to see their two brothers getting lovey-dovey. hahaha
I like how their relationship developed plus they really focused on love not sex.. so cute and it made me smile and giggle until the end ヾ(☆▽☆)
