Welllll its not really similar but these two dramas made me tear up in some scenes:
My Love Eundong
Ugly Alert (The MC went to jail, if that counts as something similar to that movie x3)
The Beauty Inside (2015) - South Korean Movie.
There's also:
A Werewolf Boy (Heard it was sad)
Can You Hear My Heart and Gloria had scenes that were moving.
My name is sam is really similar with miracle in cell number 7
I love werewolf boy <3 I highly recommend that you should watch it.

Whoa! Thank you guys! Now I have to prepare for tessues! （/TДT)/
