Just as Shen Bijun was about to take action, out of the corner of her eye, she caught sight of a scar near his ear.
Back then, when they carried out a mission together, she was caught off guard and ambushed. It was he who pushed her away in time, taking a knife for her.
That knife stroke ran from beside his ear down to his neck.
Had it gone any deeper, it would have sliced through his carotid artery, and he would have died.
His life was saved afterwards, but he was left with a large scar, and since then, he stopped wearing his hair short and started to let it grow long.
She remembered that she specially formulated an ointment to help heal his scar.
But half a year later, the scar hadn't changed at all.
When she questioned him about whether he used the medicine or not, he smiled wickedly and said, "It's just a scar. I don't care about my looks. Besides, this is the mark of when I saved your life, 518. Remember, you owe me your life."
