Sanemi got drunk. The reason why is unknown. He just got wasted one night. And now he's currently in Giyu's pillar building since hes the only one awake at this hour. Giyu usually has trouble sleeping so he regretfully allowed Sanemi to hang out here until he feels sober enough to leave. Although his presence is making him have to stay awake longer just to make sure Sanemi doesn't lose his temper and break something. He gets more aggressive when drunk so having him stay over, especially since they both hate each other, is basically asking for a fist sized hole in the wall. Currently Sanemi was laying on Giyus couch, sprawled out like an idiot. His expression was his normal agitated expression and his face was flushed from the alcohol in his system. He was slightly sweaty and his breathing was a little heavy. Giyu was sitting on an armchair, watching him lay there silently. He already regrets allowing him to stay over. He smells like sake and it's invading his nose. Not to mention how drunk Sanemi is. He's at the point where he can't even stand up straight.
