I dont remember much just that

• its a manga
• maybe a shoujo
• the male and female lead are school goers
• the male lead is overprotective of the female lead an treats here like a mother
• the female lead is I think an airhead(not sure)
• maybe they r childhood friends too
• I remember this one scene about where the guys fixes her button or something of the shirt
• the girl maybe wants him to be away but he continues acting like a parent.
• the guys secretly harbours feeling for the girl but maybe the girls doesn't know yet and she also falls for him slowly later (not sure)

Now i know its very similar to Osananajimi ga Mamasugite Tsurai (My Childhood Friend is Overprotective)

But I just read that and its not it. Very similar but not it. Its been yrs since ir end that so definitely not something from 2024-25, I think, but I can't be one hundred percent sure.

Also if something is close but doesn't match one of the points I mentioned, pls still mention since my memory of that manga might not be completely correct.

Kindly help me find it I rly loved it, It was very cute Thank you in advance :)
