I left it half way cuz I found kazumo behaviour very arrogant and mean (opss he is tsundere I hate tsunderes) but he got very good character development after few chapters I like it , and uke is like a only daughter of house they(his family) care soo much about him lol and as for jin he is good seme ... For the old time manga it's rare to see cheerful type seme like jin .
