I enjoyed this drama, because of its relatability to real life. Each episode's story was good and had connectivity. I'm a fan of Yamashita and I liked Karina in this too. The ending showed some character growth and was satisfactorily concluded.

The title didn't fit to the story and they tried to explain it when Asahi is talking about the summer. It should've been called Promises. LOL. I don't mind a slow build to romance, if the chemistry is shown or at least hinted at in a more obvious way; burning looks, accidental moments, touches, closeness, things like that. Or even if we were given some good kiss scenes, hinting at the chemistry. None of the couples really had that, including the owners of the cafe and restaurant on the beach. Their chemistry was on level of middle school kids and not adults. [Even in real life, if a guy or girl is as unreceptive or cold as these couples, we loose interest and move on.] The writing just wasn't strong enough beyond friendship and life trials. I would've given it a higher rating if the romance part of it was stronger.

A little too much time was spent on the teen romance, which wasn't even needed. The "Ricky" character and everything involved with him, was just dumb and felt like useless filler, when it could have been used on the ML 1 and FL2 (Asahi and Natsuki). Also the billboard part was too drawn out and repetitive; like they were beating us over the head with it. Twice was enough to make us understand Asahi's dependancy on remembering promises.

The production was good for the most part and the scenery was nice too. The music was decent, but nothing really memorable, at least I didn't have to mute it like in a lot of other dramas. There wasn't any FX that I can remember. Overall a solid 6.5/10, but I doubt I'll rewatch all of it.
