Kaichun HE, Zihan LIN's boyfriend, had a mysterious identity: he needed to be recharged and carry the power bank with him everywhere he went, just like an electronic product. Still, they got married, and the truth eventually came to light. Kaichun is actually a PUA member. The organization had caused physical and mental harm to many women. The fake identity "Batteryman" was to cheat Zihan LIN and realize the purpose of mind control. When HE was proud of his "brilliant" achievements, he did not know that he had also become a victim.
