If you like lighthearted romance dramas, then you should watch "My Little Happiness".

The story is stuffed with clichés, but it didn't bother me at all because of the good acting and chemistry of the leads Cong Rong and Wen Shao Qing. Dialogues, camera, editing, continuity are all on a high level.
Wen Rang is a little bit annoying, as I can't relate two is apathetic behaviour.

It's an entertaining drama that never becomes boring...
...well except of the last two episodes that very very disappointing:
The last two episodes don't fit to the rest: neither in terms of quality of production nor in the story itself.
My guess: due to the COVID pandemic and maybe as a tribute to the medics and volunteers they added this "earthquake" storyline which is totally unnecessary and lacks of realism. Realism that can't be achieved with a drama budget where a natural disaster is just a sub plot.
Second: How can Wen Shao Qing decide on his own to have babies with Cong Rong and announce this in front of the whole family without having discussed this with her in advance?
This doesn't fit to a young, well educated, ambitious and career-oriented couple as they appeared in the episodes before.
