I found this on Echizen's Twitter. I think they gonna make another pregnancy counseling session with Sakura & Tsubaki again.

I don't know when they gonna finish this one and I heard a rumor that Kase (Sakura's boyfriend) will make a baby with Tsubaki while Hajime with Sakura again.

I don't know if this is true. If it is, I guess Kase is the only side male character that lose virginity in the story. He got a special privilege by Hajime. XD
