I recently watch the ongoing series named one ordinary day (played by 김수현)
I surprised that the main role is asthmatic

So i wondered, is there any korean drama with asthmatic male lead?

I haven't found any Kdramas with ML with asthma, but there are a bunch of Cdramas with ML or second ML, also thai. I know of a Korean movie with a second lead with asthma tho.

I want to know

IIRC, Mimicus has an ML with asthma.

Time To Hunt (2020)  -  I think the asthma was pretty well portrayed, but, warning, it's definitely rated R.

Totally a good watch if you like action thrillers tho.

Here are a few  Cdramas with male leads with asthma:

Well intended love: s1 eps 2 &5, s2 eps 10,12, & 14

Embrace Love: eps 10, 11, & 17

Hello. Joann: eps 4,8,21, & 28

Back to 1989: eps 2, 3, 6, & 18

@angeliviki2022 thx!

Your honor - this one is turkish (or Israeli, idk), and prob rated MA, but I really LOVED it. Eps 1,2,3, 4, & 7
