Manhua

swoul swap, strongest sword master into suicide eldest son. he is very well manered, doesnt burst into anger, knows when to show his fangs. he is polite

well.. this is a good read. it shos (yaoi) on the tittle, but i hope it continues normally like a manhwa novel without too much romantic session. surpisingly its OMEGAVERSE but only to those who awakened powers. main character is the calm type. yuther. i think the male lead is the prince,
