Help to find this manga title, please!

May 30, 2024
It's About a high school girl who likes (not love) an old man's style, and the MC Is a regressor/ a person who back to the past.
because the MC is someone who goes back to the past, he still maintains his behavior as an old man as he was in the future.
So The girl who see the MC (a young MC) behave like an old man becomes interested in the MC.

I have searched that Manga for a long time, but still couldn't find it.

Please and thank you.
