This is, by far, my one of the closest recommendations for WIFTY:

- The male lead is a green flag, always helping the female lead.
- The girl develops feelings for the guy first, but he falls even harder.
- It follows their journey from high school to college.
- The setting is shot beside the ocean, providing a calming atmosphere.
- The OSTs are nice.
- The names of the main male lead and second lead are mixed up.
- It features a slow burn love story.

However, it lacks:

- The strong friendship dynamic present in WIFTY. Most of the female lead's friends are girls, and they don't show much bonding between them.
- The inclusion of family life in the end.
- Unlike WIFTY, they face major problems in their careers and love lives.
- There are love triangles.
- It lacks proper kissing scenes. (because the FL is too young when they shoot this)
- It is quite long with 32 episodes.

If you've finished all of the recommended dramas, there's nothing wrong with giving this one a try. Maybe it will be to your taste after all.
