However, our considerate protagonist worries that she may be working too hard.

Episode 3: Chinatsu Nekoe
After the turmoil of the Saiga family inheritance dispute subsides, Chinatsu ends up mooching food and drink at the protagonist's house. Naturally, instead of trying to fit in and live happily with everyone, she keeps teasing everyone (well, mostly Nanako).
Eventually, Chinatsu breaks a precious heirloom vase, which sends Nanako into a rage. Though it really was an accident, the result is still Chinatsu's fault for being careless.
She admits her mistake but can't bring herself to apologize sincerely, and instead runs away from home. Will she find her place in this family? Or will their brief time together end here?
