Hello guys

i'm looking for a specific manga where one mc (male) speak another language because he spent 4 or 5 years in Taiwan (i think, not sure) with his grandfather. His parents abandon him (not really abandon but they argue before the kid for the custody) and his grandfather decides to take him.
It's not the main plot. I don't really remember. But i think it's a soujo with mc girl. The mc male transfers and leave alone but don't understand each other because of the language.

If you think about something, tell me please. I already search in some categories like "parents negligent" or "grandfather".

Thx you for your help ^^
