The novel was about young rookie idol (19) who was secretly in a relationship with an older wealthy man (36). One day, the older man suddenly ghosted him, told he is getting married again. He also reveals he already has a son from his past marriage.
about 5 or 6 years later i think the idol becomes very famous. But the older man son (16) has a hard life he’s bullied at school, and his relationship with his father was so bad. The thing too that the son is a huge fan of the idol without knowing of the past the idol ( mc ) and his father, at a fan meeting, the idol and the son finally meet. The idol recognizes who the son was and realized the opportunity for revenge. he was getting closer to the boy and supportive and kind so the son trusted him on everything like his relationship with his father or the bullying
The mc ( idol ) convinces the son that the way to end everything and be happy is killing himself until he actually dose it while the mc is doing to a live for it, then he showed the life at the father party or something like this.
