My sister is dating my co-worker?!
StudioPen
A story about Yomi Yakuna, an office worker stuck in a 9 to 5 job and his tale about his older sister, Aoi Yakuna, dating his co-worker, Yuki Hanaba. In Yomi's eyes, Yuki is the worst person to have ever been created. Yuki has always been very passive-aggressive, condescending, and even has been verbally bullying Yomi, all because of an incident that happened in the past involving the two of them.
Now, Yomi has to come to terms that his beloved older sister is in a relationship with his co-worker, aka his worst nightmare.
However, Yomi isn't going to take this lightly. Quite the opposite, actually. He will do everything in his power to, albeit not break them up, but make their relationship between them very tense and awkward to the point of no return. Yomi will take back every ounce of tears Yuki caused him to shed (even if Yuki wasn't the direct cause...)
Let us see who's pettiness will prevail as Yomi and Yuki gain many allies and enemies on their journey to win over Aoi's precious heart.
