Hi guys, can you suggest any manga that has this theme.
Any genre is acceptable except for Yuri or hentai.

I want the MC to completely or vaguely forgot his/her childhood love, then have a chance reunion with them.
Their childhood love may be of the same age or someone older.

Thanks in advance...

Boku wa Tomodachi ga Sukunai

Both of these sorta fit, in each case the MC didn't know about the feeling of the childhood friend, and is then reunited and has forgotten about the childhood friend/doesn't recognize them.
