hello, I need help finding this manga. My memory is vague, but I'll do my best. Is about two friends, the family of the uke has a school, of tea ceremony or flower arrangement, I can't recall. They established a relationship. At some point, during a festivity, a girl approach the seme, the uke thinks she's confessing to him, but is all a misunderstanding, because the girl is in love with the uke, and both of them tell her they belong to each or something like that.

I am looking for a yaoi manga that develops in an academy, and there is a group of five good-looking guys, and their president was in love with his senpai since his first day in school. They met during christmas, the senpai was decorating the christmas tree. And then the senpai thought President had a girlfriend, as he was hanging with a cute girl. But, President tells him she's his sister.
