The comments are acting like geonpil was obligated to reciprocate the original guy’s fee...

Well , people don't realise how dangerous these kind of ideas are in real life... this is equivalent to them thinking that a girl has to sleep with a guy just cuz he paid for the drinks and dinner... Though yeonseong is kind and didn't expect anything else in return , but geonpil thinking that the only reason yeonseong is helping him is because he want to have sex with yeonseong and that's the only way he can repay his hyung is almost sad...
