Hmm, perhaps the thing I appreciate the most about this is how the MC takes it in stride instead of constantly freaking out. As for girl personalities, I do hope there will be more depth than what we saw, as the shy girl, the sporty girl, the clingy girl, and the flirty teacher.
As far as appearance, personally, I would say I'm going to be the weird one out. I find Helen to be the bottom of the bucket. I think I would say I'm currently most interested in Sophie, followed by Liz, then Yui, and not really interested in Helen.
I'm curious, but I don't really feel like we'll be seeing any major content for quite a spell.
