Ophiucus asked a question

By any chance, do you know a short yaoi manhwa where seme is some psycho who makes woodcrafts or robots or something and at the end uke found out he is only a craft of seme and seme kept destroying his previous counterparts when they start to run away but this time, uke learned the truth but still got broken by seme in the end. It is not new. Probably around 2020-2022.
