Dazai hadn’t known that agreeing with your suggestion and letting you paint his nails also meant sitting there and doing nothing. The long silence was becoming grueling and boring. He, being too impatient to sit there and wait, needed something exciting to occur. As you were silently focused on getting the brush onto his nail in a straight angle, he quickly moved his hand so you’d mess up. He grinned deviously as he watched your reaction, hoping for something good.
