The story is very short, and this is the problem.
Many characters of the story have characters arcs that have no conclusion, or simply don't have much development. The mangá has 8 short chapters, so, the Mangaká focuses on the main couple, and, it's very good! The comedy is ok, and the story is very fun, but i can't let this problems go. But if the story was longer, or less "complex", I would give an 8 or 9.

The story is pretty fun and the comedy is ok. The characters that are developed are fun, so, i will give to Bra Girl a 7.
