Hi people,

I can't find a manga that I read a long time ago and it has been bothering me. It takes place at a school setting, where the uke likes the seme. I think the uke confessed to seme, who rejected him. However, the uke decided that the seme just needed to get to know him better. Each morning he would give the seme a hug and try to hang out with him. One day, the uke overhead the seme calling him an annoyance as the seme talked with his friends. The uke stopped giving the hugs and avoided him. Of course, the seme went looking for the uke and they got together.

I don't remember the title, but I do know that it was a gender bender and prooobably shounen ai if I remember correctly. Anyways, the Uke's older sister who was suppose to be married to a king from a neighboring kindgom, eloped with her lover and they didn't find out till hours before the meeting. So, they had the Uke crossdress and go in her place since they look similar (or were they twins???) till they can somehow track her down and bring her back. After that they whole story revolves around the Uke just trying to fit in with the other concubines and trying not to get caught. A funny fact I remember is that for his boobs he stuffed apples in his dress.
