I only remember part of that story. There was a group activity and the uke and seme fell into two groups, uke was not very friendly with the others . he was a pushover ? i don't remember properly but seme cheer him up . as i remember he was his only friend. and their( uke's) project was selected. and after the projects his team mates asked him to if they still can hangout . and thats how he made friends
