In Feng Xu'an's world, he was just Su Lingwei's "No. 1 Spare tire."
Commonly known as mistress.
But he is a very professional and generous mistress.
He tacitly allowed her to travel between two places just to visit her "real boyfriend".
He even brainwashed himself late at night: It doesn't matter, she sleeps next to me at night, and that's enough.
He even prepared for the worst - even if she wanted to marry that person, he would cling to her and be her secret lover for the rest of her life.
To this end, he stayed up late at night and memorized "Three Hundred Secrets to Seduce His Girlfriend", striving to do his job as a "mistress" to the extreme.
Until one day, Su Lingwei looked at his tragic appearance with confusion on his face:
"I have always only had you as my boyfriend, who are you jealous of?"
Feng Xu'an: "!?..."
So, who should he use the "advanced" methods he learned through burning the midnight oil to deal with now?
