Okay how about this
Shoto Todoroki and reader is aged up to 26
Todoroki is a pro in japan and reader is a pro in US
Todoroki got sent to help in US and met reader, after a while of working together he asked reader on a date. (Something interval about the date and so on). After a while they dated todoroki has to go back so long distance relationship. Fast forward idk how many years. Reader decide to suprise todoroki by moving to japan. Yadeyadeyada idk here.... . Todoroki proposed. And happy after after
So basically a long distance relationship
I have some ideas for the intermission like meeting shotos family and telling them they are enganged. Telling 1A. Etc
