This was a cute short manga. I don't mind the length, but it certainly ended pretty abruptly... I think if she had just confessed after seeing her mom out the door it would have been better paced.
Or, if instead of saying "I'm thinking maybe marriage isn't really a bad thing after all..." she said "I'm thinking maybe THIS marriage isn't really a bad thing after all...", that would have shown Hana her changing feelings about her.
I think that's my problem with this story, which makes me enjoy it a bit less than I'd like to (although I still like it). The characters are described pretty sketchily, relying on the reader to interpret some vague cues to understand them. One's bad at communicating and doesn't understand her desires well, but it looks more like she's sleepwalking through her scenes. The other's more forthright and is holding herself back from hoping for more, but even that isn't very clear until she explicitly says it in the last chapter. The writing leaves too much out, and doesn't show enough to give the reader much to grab hold of.
But the art's good and the situation is fun and the resolution makes sense and the fact that they actually tried to communicate with each other is refreshing, so it's not like it's all bad or anything. It's just...it feels like I'm trying to make a meal out of cotton candy. It's sweet and fun but there's no substance and then it's gone.
