Synopsis: I'll Do it For You, Oppa

My boyfriend was secretly planning to marry my best friend. I lost both the person I had promised my future with and my friend, and it felt like every misfortune in life hit me all at once. At that moment, my brother’s friend, Cha Seo-yoon, appeared. "I’ll do it for you, whatever it is." He was the hope that could turn everything around. **Original Webtoon:** [Ridibooks](https://ridibooks.com/books/5783000031), [Bomtoon](https://www.bomtoon.com/detail/oppaforyou), [Lezhin](https://www.lezhin.com/ko/comic/oppa_will_do_it), [Naver Series](https://series.naver.com/comic/detail.series?productNo=13066877), [MrBlue](https://www.mrblue.com/webtoon/wt_000071753), [BookCube](https://www.bookcube.com/toon/detail.asp?webtoon_num=250700), [MComics](https://www.mcomics.co.kr/webtoonComic/13407), [Anytoon](https://www.anytoon.co.kr/webtoon/episode/11361), [Onestory](https://onestory.co.kr/detail/H048384502), [Nate](https://toonnbook.nate.com/detail/H048384502)
