I have here a few with runaway trope, but not in all of them is time skip. I don't read BL often so all are straight stories.
https://www.mangago.zone/read-manga/i_tamed_a_tyrant_and_ran_away/ - FL&ML are in good terms, but FL is afraid that she will hurt ML with her powers, so she run away
https://www.mangago.zone/read-manga/how_to_get_my_husband_on_my_side/ - arranged marriage, FL runs away because she feels bad in her new environment and everyone treats her like an enemy
https://www.mangago.zone/read-manga/what_it_means_to_be_you/ - ML treats FL like a trash so she leaves him
https://www.mangago.zone/read-manga/how_to_hide_the_emperor_s_child/ - ML divorces with FL after just one night together. FL leaves and then it turns out that she is pregnant, so she hides child from ML
https://www.mangago.zone/read-manga/the_baby_isn_t_yours/ - FL hides her pregnancy and leaves town because ML told her that he doesn't want baby
anything where love interest chases mc after time skip, anything even remotely similar im not picky w the genre!! doesnt matter what is their relationship before time skip
