Just skimmed through episode 2 RAW and even though I don't understand Japanese, it seems like a pretty good episode.
Abe Sadayo's expression is priceless here!
The story may not be particularly exciting or interesting, especially the girl with the illness part which seems to be putting some people off from watching but to me, it's not too much of a problem because I feel that First Kiss is more character-driven than plot-driven.
The characters are all very well-written and portrayed wonderfully by the excellently selected cast (Inoue Mao's portrayal of an obnoxious but yet somewhat lovable girl is really outstanding). I really like the chemistry they all have together and it is particularly enjoyable to watch the way they interact with one another.
I know it seems like a strange comparison but First Kiss is sort of like Kekkon Dekinai Otoko. KDO's story wasn't really outstanding but the characters are all so well-written and the cast's performance and chemistry really brought the show to the point where the story very much became secondary.
I really hope the ratings for the third episode would improve since this drama is very much my favourite this season.
