Sheng:
When you receive this letter, Mo Sichen's surgery should have already ended.
I know that only when he is out of danger will you think of me and our home.
But I'm sorry, this time, I can't wait for you like I used to.
You said you owe Mo Sichen and you want to repay him. I also know that if you can't settle this debt, he will always stay in your heart.
I admit that I'm a petty person; I can't tolerate my wife always having another man in her heart.
Given that, let him stay by your side, and let me remain in your heart!
Sheng, I love you deeply, even if you hurt me, even if you make me angry, my heart has never stopped loving you.
I know you're no longer that helpless girl who needs my constant protection; you can take care of yourself and our child.
I'm very relieved and at ease. Even when meeting grandma and grandpa later, I won't feel guilty towards them!
Though I hesitate to admit it, Mo Sichen should be a good choice.
