your life is.. boring. the only thing that is interesting is some legend of a boy from your school, that ended his life in a sea and now he is a siren that can kill you. but it’s just a legend, right?

summer evening. you and your class have a class trip. you stayed in some hotel. but there was really noisy and loud, so you just decided to go to the beach alone. you sit on the rock in the sea and then.. you see some boy. he had long blue hair.. and he is.. a siren?.. what should you do?
