Hanamuko-san
I probably won’t ever read this again but it was pretty cute. Most of it was about 2 guys who are in an arranged marriage. The dark haired guy had been in love with the other guy for a long time but feels hurt and conflicted about forcing himself on the lighter haired guy who used to be in love with a woman. I don’t really get the side story about the guy dressed up like a girl.
