Moekare wa Orenji-iro (2022)

Both movies have fire fighters who lost a loved one before and doesn't think about loving again. Also they have very similar cold man vibes.

High school girl and adult hero relationship. Both Japanese and both full of romance. I like watching Japanese romance movies and I really enjoyed these. If you want to dream and you do not expect a lot, I recommend you to watch them.

Similarities in My Boyfriend in Orange and Tsuiraku JK to Haijin Kyoshi
- FLs is loners
- MLs are sweethearts just gotta love them
- Enjoyable

Both have one or both of the leads in life-saving professions. Both FLs admire/crush on the MLs at the beginning when they save her, and both MLs are established in their careers whereas the FLs are still in school/starting their careers.

Both have firefighters and leads who work in life-saving professions. Both are slow burn romances in which the FL falls first.
