Matsuri-chan's secret boyfriend?
Matsuri: "Oniichan, I'm pregnant"
Anonymous: (hug) (scram)
Well, the dialogue seems to suggest that they haven't seen each other in a month, but she's glad she got to see him. He asks if he can hug her and then says he's got to go since it'll look bad if he stays. She asks if she can go along with him to wherever.
I haven't told the others about this, I don't know what I should do (Oneechan tachi ni hanasenaishi doushiteiinoka wakannai yo)
What have you done?
