This manga can end in one chapter. Just make her your waifu man and you're set. Wrap it up with a marriage and maybe end the whole tjong with a glimpse of their child holding both their hands.
I hope the manga doesn't go the same route the LN with, a female love rival appears from what I read, they changed some stuff already in the manga, which is good imo. Anyway some development finally happened in this chapter. Thx for the translation.
