The vibe is the same for both drama:
* Song kong in the cast, in both drama ML have a handsome character. he's so famous in community and try to get attention of FL
* both are Webton adaption
* both are in educational place
( nevertheless: Art college
Love alarm: high school)
* in both drama there's a Love triangle though the new ML steal the FL's heart

The first drama came in my mind for nevertheless's recommendations was the innocent man:
* both have TOXIC relashionship that make you weired and mad
* both have naive FL
* both have a ML who flirting with women and hurt the FL's feeling
* both FL have psychological problems, they are insecure and having problem in their relashionship with men

*both are about zombies
* both have wonderful characters (heroes)
* both have action scenes fighting with zombies
* both have villains that endanger people's lives
* both keep you on the edge of your seat until the End
