please help me find this slice of life manga of an alien who gets lost in the house of a grandma who sells bread. if i'm not wrong the alien came with an egg-like ufo, the alien goes to school too and has an antenna above his head that he can hide, i don't think anyone in the story knows that he's an alien.

my description might not be accurate tho, so please tell me if you know a manga that's almost similar to what i described. thx guys ✿
