Hmmm, I quite agree with what Yeonha's said in some parts. Especially it's soothing that can be rather boring.
It's sweet, but not really kicks in.
But I feel this is very natural in terms of the process, whether how often the theme is overused.
Both characters can stand in equal. I think it's good because they were not made as god-like creatures with many wild imaginations by people around them. This also might be the first time where I feel nothing special with the two main characters.
When I read the first 2 chapters, I wasn't in their world yet, but the addiction slowly increased.
On the other side, to be honest, I still feel Sakura to Sensei works better. A world based only belongs to both of them. But it doesn't concern the instability of teenager's love life which is good.
This manga is less fun after getting into a new challenge in their relationship (remember, this is a review per more than 15 chapters on OM).
