The Promise (2023)

Almost same story . In both series th MLs ran away after fell in love with SML or due to some misunderstanding

Phupha| Nanfah is the Thai prequel to "The Promise"
You can skip prequel and watch the sequel for better understanding.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Similarities:
- friends to lovers
- seperation due to misunderstandings

...you will see if you watch the other
