Hello,I'm looking for a manga where a girl is a singer/idol & she ends up with a normal/friend guy. I think there was a love triangle with another girl Idol,but not too sure...it's been a long time since I read it & can't remember the details very well.

This is our sacrifice...
Your hotel-heart won't be so vacant

I don't remember if there was a love triangle, but maybe Berry Dynamite ?
