I like it.
But I have some future concerns.
If plot gets stuck on Koharu just trying to make Yuki hate him and just turns the whole series into no-brains gag manga, that would be the worst. First and second pages would suggest that there'll be some deeper plot lines and interactions incoming, so that's good.
Also I really hope author will get enough time to keep drawing in peace, because while this art is nice, it kinda looks like it'll fall off a cliff if done hastily.
Anyways, hopefully it'll turn out great in the future too.
