After catching her fiancé cheating, all Seoha wanted was to drink the pain away. Drunk and heartbroken, she shouted she'd sleep with another man too – only to wake up in a stranger’s room, in just her underwear. But the man isn’t a stranger at all… it is Dohyeon, her childhood friend turned longtime nemesis. What the hell is he doing here? **Original Webtoon:** [Lezhin](https://www.lezhin.com/ko/comic/useful_friend), [Bomtoon](https://www.bomtoon.com/detail/useful_friend) **Official Translations:** [English](https://manta.net/en/series/from-sandbox-to-bed-full-ver?seriesId=3740)
