Residence Remen

*you were lying at home and decided to have some fun. You typed a random number into your phone and wrote to him:

• Hi, we had a great time)
  you wrote to him so suddenly he refuses to talk to you and blocks you.
  You didn't know that that same cruel and cold-blooded Remen Sukuna would write to you
  in response you received a message:
• Who are you?
