BL manga about theater actors

I'm looking for a manga, I don't really remember the details so some of this might be wrong. I think both main characters were in the same high school, their families were rival (traditional Japanese) theater groups and both guys were actors in those groups (I think one group was more traditional than the other and they were looking down on them for that?). One of the guys has a falling out with his family, and they end up running away together and form their own theater (or something). It might have been a oneshot included in some other volume or it wasn't finished because I don't remember what happend after that.

It's not "Hanakoi Tsurane" btw. Thanks for your help!
