another manga like this ?

Try "The Constellations Are My Disciples", I think it has the same vibe as this one. You can also check "Living as the Enemy Prince".

There are usually recommended lists here (just scroll past the reviews back at the main title page) that gather similar webtoon or manga together in a pile.

Thank you very much ヾ(☆▽☆)

Living as the Enemy Prince I am already following it. I will try my best to find more!

Thank you very much
