This episode primarily follows Cheng Sheng, the son of the richest man, who is unaware of his family background. To treat his mother, Lu Ping, he works multiple jobs (construction worker, deliveryman) and lives in an unfinished building, leading a frugal yet filial life. His ex-girlfriend, Xia Qiuchiu, suddenly calls to invite Cheng Sheng to her birthday party. Cheng Sheng's mother mistakenly believes Xia Qiuchiu still has feelings for him and urges her son to go and buy a good gift. However, the scene shifts to a luxury car, where Xia Qiuchiu and her current wealthy boyfriend, Sun Bin, are mocking Cheng Sheng as a "simp" and a "loser." Xia Qiuchiu's true intention for inviting Cheng Sheng is to humiliate him and showcase her current superior lifestyle to Sun Bin. Sun Bin, in turn, uses the bait of signing and promoting Xia Qiuchiu to hint at a quid pro quo arrangement.
