Its not that massive of a drama... but still. For someone who didnt want to even give her number to not be friendly, as if she has a good sense, she not only went to his house (by chance she had Mayu at the start) but also let him hug her for quite a while. Not to mention she opened up about her relationship problems with a guy that recently confessed to her.
Midori-san... shes cute, but very troublesome.
