I was surprised by this drama, because I really appreciated these kids growing up and the portraying of their parents. Music was magical, except that some transitions between emotional scenes to funny scenes were very bad.
The actors are good, some are perfect.
I loved Em's mother character, strong and affectionate; and who cannot love the caring grand-father?

How to define this drama? Including different sort of couples, at different steps of relationship was more realistic that specific genre as BL or classical romance. Adding a character with disability was great, and the story not too simple about it.

I read a lot about wigs in the comments... honestly, it was not such a big deal for me? because in thai drama, I often find the hair styles totally strange and not good-looking for the actors; so in this show, it was not so shocking...
A funny detail : there is a lot of nostalgy about the previous decade, with new technologies creating new modes of communication; but for me, being in a relationship for about 25 years, I haven't this background; so I wasn't emotionnaly connected at any of these "first uses"... so it was like a documentary for me, "how was living the younger generation who is now 20-30 years! " ah ah ...

But as a mother, this drama was sweet about the parenting moments... and being a very romantic person, I was touched by the freshness of the different couples and the little moments of their evolution.
