It's just yuta's dream in a flashback ╥﹏╥
It's not his dream it's flashbacks in flashbacks actually after S dropped Yuta home after the hospital. The bastard son-in-law raped him. Yuta called S and knows S phone number since the first time they met.
S cameback at home to take him at his own house to protect him from Yuta's family in law.
it seems like they had an actual relationship or something this goes deeeep
