100 days in Europe

It’s honestly the best straight romance I’ve ever read, no unnecessary miscommunication or drama and it’s super entertaining.
I also saw you have veil as your pfp, the mc’s have a similar dynamic and vibe what-not.

Need straight romance MANGA recs thats finished or maybe has at least 20 chapters, preferably slow burn but idrm either way!
