At the end was that Shikimori sensing bad luck incoming but then getting confused when nothing happened. Then we see the new dude messed up? I found it hard to follow along this chapter but it looks like hachimitsu gunna get herself a bf.
Teacher was totally in the right on this. If he noticed, then other less forgiving people will notice. Especially if Arase's getting carried away giving hickey's
It'd be funny if Sumi somehow ended up winning in the long run. Like, he does get together with Chizuru but it doesn't work out so he calls up Sumi for consolation and ends up with her.
