In which episode did Hugh kiss her boss?

None of the three girlfriends of Hao Yuan, who was absent from your play, is a female boss.

I guess it's about the heroine Koharu. That was in the second episode.

Hao Yuan is very kind. He came to Zhu Tao's restaurant with Mao Xiaochun. Who knows that Mao Xiaochun, who drank badly, just vomited. He turned around and kissed Hao Yuan behind him. Hao Yuan was caught off guard by the kiss, full of vomit and asked for it. Zhu Tao answered a friend's phone, leaving only Hao Yuan and drunken Mao Xiaochun to leave in a hurry.
