He joins forces with others to post malicious negative reviews and uses them to extort money. Even after the owner reluctantly agrees to issue a refund, Chen continues to harass him. Following the delivery address, the owner finds Chen's girlfriend, Su Man, and exposes Chen's hypocritical behavior. Seeing his true nature, Su Man decisively breaks up with him and offers the shop owner her support.

After the breakup, Chen continues to harass Su Man by demanding reimbursement for their dating expenses, ultimately ruining his own reputation. Meanwhile, the flower shop becomes a hit, and the owner and Su Man form a genuine bond as they move toward a peaceful and happy life together.
