When he woke up, Shou was incarnated as the eldest son whose father did not care for his mother and ran away to the palace for a living. By chance, he became the blood bag of the deposed prince. He accidentally discovered the prince's secret and kept it secret for him with good intentions. Gong didn't know that his secret had been spied on, so he became more and more gentle to Shou. The secret jealousy he had unknowingly flew into the sky. He was possessive and accidentally exposed his thoughts to Shou.
"Hey, you are the useless prince"
"As for me, I am the unloved legitimate son. Don't you think we are a good match?"
"No, you don't deserve it"
Intention: Relax, relax
