Sou is so coming along with him to the city, isnt she? And I guess Nozomu will ask his grandpa to babysit them while he clears up the misunderstanding at least with his ex classmates.
Oh no the boy goes back to the city, time skip 10-20 years later. Both have a partner. They greet each other at some point and remember the past, etc. Dont mind me, I’m just blabbing nonsense
