Rinsama_'s manga / #short stories(1)

It's shoooo kyuteeee!! I had the physical book of this. I bought it because of the art, but the stories are so adorable >< So it's a series of one shots: 1) serious girl who corrects wrongdoings met a scattered-brain guy.. Somehow they grew tgt 2) a beautiful petite girl who's fierce goes out with a boy who promised to make her happy. Accept her for herself and goes along with her whims. Love this the most. 3) a quiet girl x popular boy (quite normal so meh)
