Caffeine

Chan-Woo owns a coffee shop in Seoul. His little brother Jung-Min is living with him while he looks for jobs. These two brothers share something in common. They both have the hots for one Da-Yeon Sung. She’s a childhood friend of theirs and now lives in Seoul as a model. Jung-Min’s the one who got there first however, and is now dating Da-Yeon. Looks like Chan-Woo has to just wonder what could have been… But Jung-Min’s cheating ways end up bringing Da-Yeon into Chan-Woo’s arms. And when Jung-Min discovers the two together, things look like they’re about to get ugly. But…is this really happening? Is seeing his brother sleep with his girlfriend really turning him on?! Still, Jung-Min can’t let his brother get away with this. Like the bitter taste of caffeine, these sexy thrills can be dangerous but addicting... (Source: Lezhin US, edited)
