The Sugar Daddy is My Bother

Synopsis

That night when I returned to the dorm, I finished washing up and was about to do my skincare. But I noticed my face cream was clearly used up more than before. I was just about to walk over to my roommate Rene's bed and ask her about it when a stream of floating comments suddenly appeared in front of my eyes. "Using a bit of face cream and she can't handle it? Our girl is going to steal your sugar daddy!" "The female side character is so boring and cold, like a dead person. That innocent nice-girl type is outdated." "Once the sugar daddy sees how lively and bright we are, and how the female lead keeps climbing up using every chance she gets, he'll definitely be obsessed." I frowned. Sugar daddy? The one who just sent me back to the dorm… was my brother.
