i, actually, like this manga. it is really cute, and you can tell the character's feelings for each other are true and it's sooo cute~! and i also like the fact that it spans out over a period of time, and it's not just like one week. that was a real difference from other shoujos.
and they didn't sleep together! in the year that they were together! i know, whaaaaaaaaat?!?! i really liked that, whether they were sleeping or not wasn't a really big element; it was just kinda cute, and he's like, oh it's really okay. i think that was really adorable. (at least i'm pretty positive they didn't lolol)
of course, as others said, it's very... well... shoujo lol! which isn't a bad thing, but at times i was like.. wow, of course that would happen just at that very moment, or wow, that was at a convenient time. or wow wtf is the author thinking, this is stupid. plus not many other characters other than the main two were developed. they tended to disappear soon after they were introduced.. lol.
still, give it a try. i think the expressions of the characters and the art were adorable if anything else. and of course it's pretty predictable and eh. but it's still a good time waster, it's not completely trash. 😀
