I really liked the others, they where kinda fluffy. I skimmed 4 because im a weak person with a weak heart. i have to say yes he is the worst, for a man to love his family so much but still go after another woman is sick. The girl is not a bitch if anything she is a victim kinda like stockholm syndrome(but not that per say because she was not kidnapped and all) thats just my personal thoughts tho. i do recommend reading the other characters they are good.
Ah we need more yaoi like this beautiful art, real plot, fluff that makes you heart flutter to me these are the best type of yaoi ^^
