It was ten years since they met when junya was crying (kyouichi was 12). The mangaka shown us the story five years later after the meeting, when they are now stepbrothers (kyouichi is 17). They last chapters of the manga shown us five yrs later after they have first gotten together (junya is back, and kyouichi is 22).
Ten years in total since they met

It was mentioned ( http://www.mangago.zone/read-manga/touch_blue/mf/v01/c003/29/) that it was 10 years ago that they met when Junya was seen crying. Currently Kyoichi is in highschool so probably around 17 yrs of age. Does this mean Kyoichi was no more than 8yrs old when they met ( http://www.mangago.zone/read-manga/touch_blue/mf/v01/c001/3/). But with the seen of him giving the hanky and coffee, he looks already in highschool or maybe it's just me wondering. (づ￣ ³￣)づ
