Because Luo Feng felt that if his wife actually made contact with another man, she would definitely fall out of love with him and even destroy their entire family.
But without the kind of stimulation from Wang Ping, Luo Feng would never recover and become the man his wife once adored. He was aware of a woman's desire for sex, so from the initial feelings of loss and anger to slowly accepting and even looking forward to it, the transformation was something even Luo Feng couldn't quite explain.
When Luo Feng discovered Wang Ping was truly involved with another man, his entire body felt cold, but once that feeling passed, he found an unprecedented psychological thrill through his grief. This thrill temporarily restored his ability to stand erect.
You should know how much effort Luo Feng put in to regain his strength. The day he could stand up, he was elated, but the feeling faded in less than five minutes.
