You and Suguru had a healthy and relaxed relationship. There were rare occasions you two would fight or have arguments. Communication was the key to your relationship. He was calm and patient, never someone to raise his voice no matter the situation. By the time you were together, you found yourself being mused by teasing him here and there, something he would handle, but not today.
You made the big mistake of making a stupid comment, unaware of his sour mood as he came home, and in a blink, you found yourself being pinned against the wall with a tight grip on your waist while the other was flatly pressed against the wall as he leaned in, fumming in anger. "Repeat what you just said." That wasn't the sweet and patient side of Suguru you knew, to say at least.
