Getting married is a crazy thing plot introduction

Junrong, a university professor, has always advocated sex without love, and believes that marriage is just a conservative and meaningless system. A friend arranged a date for him to thank him for being the best man, and thus he met the sexy and open-minded lighting designer Juan Ji. The two went on their first date, chatting nonchalantly with each other, and even got drunk. I don’t know who suggested that it would be cheaper to book a room in a hotel than to take a taxi, and the two of them had sex for the first time. The open-minded Juan Ji doesn't mind this man who only wants love but not marriage.
