Lately, I've noticed many different cdramas that are anywhere from 2 - 15 mins long and I've been watching quite a few. Some good. Others not so much.

If you've come across good ones, could you recommend some please? 

Ones I've already seen are:
Night of Love With You 
11 Left 
Seal of Love 
Untouchable Princess 
Mission in Parallel 

Thank you for the recommendations! I'll have a look. :)

I just completed The Killer Is Also Romantic and liked it! 

Except The Crush these aren't Chinese but I still recommend:

140 Ji no Koi

One fine week

 My Fuxxxxx Romance

≥75℃

1 in 10000

To My Beautiful Woo Ri

Missions of love

The last 2 I absolutely recommend have a duration of 15 min (with intro, which you can also skip) but a lot of episodes:

Oshin 297 episodes, so that means 74h

Manpuku 151 episodes, 38h well invested ;)

My Bossy Wife 

it definitely isn't a drama with a very new or a fresh plot but it's very light and nice to binge watch during the weekend

https://mydramalist.com/734507-my-honey
^ this is a fluffy romcom

^ this is similar to Night of Love With You, with both of them having some sort of manga characters
