Who doesn't want to watch a light hearted drama after working on assignments for whole day. Yes this is the one your looking for if you are stressed or need something to improve your mood.
Things I want to address
1. Female lead is mature and smart. Solves her problem without being a crybaby.
2. Male lead looks cold in beginning but actually is a warm hearted person.
3. Chemistry between the leads is appreciable. No unnecessary scenes.
4. Second lead couple are both capable and their story is harmonious.
5. Their whole team ( cat, k, fatty, manager, Cheng's brother and former member) along with main leads have beautiful bond in the story.
6. No antagonist who plot against main leads, so no stress.
7. Gaming scenes are shown very well in a way you don't get bored.

Conclusion: There are many e-sports dramas that try to include romance and comedy in their genre. But I think Falling into your smile did justice for e-sports rom-com.
