No, ,red hair guy loved the older version of the black hair guy (the person who killed the red hair guy from beginning)
Red hair saw this black hair guy as companion and friend when blk is still 16 but this black hair guy already liked this red hair guy, but then **spoiler** when red hair guy died on the game the black hair guy spent his time trying to go to blk hair guy world
Time skip blk hair guy become Adult and finally got into red hair guy world, but blk hair guy he spent decade waiting to red hair guy only to find out red only spent few months and doing fine (since he just want to live and not be on the game)
So when they both saw each other they are happy
But they still have mission and also in this time red still don't like blk romantically and thats is just where they started liking each other romantically
Is this going to be groomy, like does he (26) fall in love with his 16 year old form? Or does the 16 year old form fall in love with him and he reciprocates?
