Can anyone recommend me a manga/manhwa that can make me cry?

I highly recommend Efforts never betray and Gorae Byul - The Gyeongseong Mermaid

In a good or bad way? Bad: https://www.mangago.zone/read-manga/madman/

Good: https://www.mangago.zone/read-manga/like_a_butterfly/

1st is BL & 2nd is not.

For short stories mainly 5 ch or below I’d recommend:
Spring snow (BL) - 3 ch
10 years where I loved you the most (BL)
This witch of mine - longer side
Virtual illusion (BL) - one shot
19 days (BL) - longer side, sadder as you go on I SWEAR
Yoake no uta (BL) - decently long
