Why did he eat sweets so often? Especially in tense situations. Just why did those wonderful creations make him feel so much better?

Perhaps he had an addiction. No, that wasn't it. Yes, he did seem to be seen eating it like it was a hobby, but he didn't feel the overwhelming urge to go and snarf on cake like real addicts do with drugs of some sort.

The sugar content. Yes, that seemed to solve it. He had at least 500 teaspoons total a day of sugar content. The said additive obviously stimulated his mind and he made better judgments and decisions with it. It was his companion. His partner in crime—so to speak.

…Wait, did this mean to say the genius L was stupid without his sugar?

L looked down at his strawberry cake. His eyes narrowed at the pale pink tinge of the now less appealing frosting. Perhaps he would have to skip dessert this time.
