Su Jin was merely a miserable man who had endured immense suffering in a past life, which he was unable to comprehend. Someone who fell in love with the wrong man and hurt even his one and only family. Ultimately, before he could fully appreciate his second life, he was informed that it had been granted to him in return for Ji Yoonjun and Lu Ming's sacrifice. Even the thought of it makes him regret all he has accomplished in his past life.
Mo Xuejing wanted to tease him more because he thought he was too weak-willed. The more he observes people with weak wills who were given opportunities but did not value them, the more he feels like stepping on them.
