Looking for old romance webtoon

[ark-exodia3]

I think this is 2010 or 2012 korean webtoon

the story is about love and break up, mc was working adult i think age around 25 years or more who meet a female college junior aka kouhai when he went to bath house or something, they chat and start relation ship there. I remember this webtoon was quite famous and i remember the ending where the male mc visit the female mc at some place like cafe or bar and tell her he was his number 1 fan( they already break up and started as friend)

female mc have orange hair i remember it
