Did he come to Hengyuan city? There weren't many descriptions of supporting characters for this period of time in the original novel. For this reason, even Jian Yiling didn't know why this man appeared at Hengyuan City at this time.
She didn't know what sort of ending this man would have either. She also didn't know how the conflict between him and the male lead got resolved. This was because she didn't yet have time to read the ending. When she read up to the part were Jian Yiling died, an accident had happened at the institute and thus, she got sent to this world.
The only thing she knew was that this man had a bad temper and a bad reputation.
The way he did things was unreasonable and never considered the consequences. He didn't care about anything and that included his own life.
He wasn't afraid fo death. It was his family who was afraid of his death.
