FL Totally forgets about her ex when she meets the Dynamic ML

• Love Better Than Immortality (2019) (more complex than just forget about FL's ex... I don't want to spoil you anything so I'll not explain further. Yet, ML is jealous and quite possessive, quite teasing too)      
• Eternal Love (2017) (complex story though... fits what you're looking for! ML is quite possessive too)
• When the Camellia Blooms (2019) (she doesn't love her ex anymore (even in the beginning) but she has a kid with him.. She has suffered from their story, so she is still stuck with that. ML is jealous but in a super cute way and not that much!
  
• Before We Get Married (2019) (it's about the infidelity so... She is forgetting her current bf not her ex... ML is teasing and jealous!)
  
• Shanai Marriage Honey (2020) (Fit what you're looking for! Super cute and sweet ML)
  
• Long Vacation (1996) (Exactly what you want, however it's slow-burn romance and he isn't that jealous)

 SoundsGood:

Thank You so much.

You're welcome :)

• Pride
• Lovers in Prague
• Drunken To Love You
• Love is scenery 
• Discovery of Romance - though the ML is the exBF of FL who comes back into her life when he has a new BF. 

Thank You so much, I saw Pride it was really good and I dropped Discovery of Romance because after watching Eric's Overwhelming Presence in Miss Oh I  couldn't watch him fight over a woman. I am definitely going to check out the other 2.
