Helping Yang Wenqi solve this issue was just a matter of a text and a phone call for Chen Feng. He didn't have to use any favors, and instead, because of the lead he provided, Qin Zhen managed to catch a group of scammers, which improved his performance and earned him recognition. So now, he owes Chen Feng a favor.
Yang Wenqi, on her side, was genuinely grateful to Chen Feng, because if she hadn't sought his help, the scammer might have hurt her or assaulted her. This concerned her personal safety, so she was naturally very appreciative.
Therefore, she naturally suggested treating Chen Feng to a meal as a token of gratitude, and she was quite insistent, even saying that if Chen Feng didn't accept, it would mean he looked down on her.
Chen Feng certainly didn't look down on her and agreed to her invitation to show his respect.
