Chapter 7

“One night stand or partner. Choose one of the two.” The man she had been in love with for two years made a strange suggestion. Is this man serious? Ji-an’s crush was blatantly spitting out words that could be used to get her accused right in front of her, but she couldn’t say anything and just stood there blankly. ‘No matter how much I have a crush on him!’ But her good self was the bigger problem. She followed him to a fancy penthouse suite. “A meal, a simple glass of wine, and one night. Isn’t that the perfect package?” **Original Webtoon:** [Ridibooks](https://ridibooks.com/books/5285000445), [Naver Series](https://series.naver.com/comic/detail.series?productNo=11719970), [Bomtoon](https://www.bomtoon.com/detail/metatoon015), [Lezhin](https://www.lezhin.com/ko/comic/bad_animal), [MrBlue](https://www.mrblue.com/webtoon/wt_000065667), [BookCube](https://www.bookcube.com/toon/detail.asp?webtoon_num=241071), [Toomics](http://toomics.com/click/intro?cno=8913&pid=conist) **Official Translations:** [T.Chinese](https://www.webtoons.com/zh-hant/romance-m/with-the-beastly-boss/list?title_no=7253)
