I honestly think that the first story is really crappy. No offense, but it's irritating when I see that Ayumi is always losing self-confidence as well as having to yield to Keita. She isn't honest, tells a lie, then keita did ignore her and blah blah, she'll say the truth in the end, etc. Soooooo boring. All the three chapters are similar only with different "3rd wheels" coming in to spoil their relationship.

I do like the side stories though. They're kinda sweet and cute, at least much enjoyable than the main story. No irritating and unnecessary dramas, just something direct although a bit cliche scenes. Overall, it's okay! No good for the main story tho!
