WULFRIC felt cold sweat dripping down his back. Although Aster asked that question with a smile on his face, the emotion in his dark obsidian eyes told him that he would seriously slap him if he didn't give a satisfactory answer.
He gulped. In situations like this, it's better to just tell the truth. The more excuses he made, the worse it would be for him.
"It's on that day when that trash hired some goons to harass you at school," he said honestly.
Under normal circumstance, he probably wouldn't remember such an event. Despite having a brain that could remember everything if he wanted to, he usually chose to 'file' things he found useless at the very corner of his brain. If needed, he could easily 'retrieve' them.
Mini-theater:
Aster: Are you keeping any more secrets from me?
Wulf started to sweat profusely: (´-﹏-`;)
