Elise who watched everything constantly kept asking him why they did what they did. Hiw could he explain the escapades of adults to a five year old girl?
He could only make up excuses telling her that it's just something people do when they care for each other but fearing that she would go around kissing unknown boys, he told her that it only works when people kissed him because he had superpowers.
Elise was skeptical as it's not the first time she seen people kiss but he also had a answer for it. Because his power of love was stronger than anyone in the world which was why everyone wanted to kiss him when they were sad.
Elise thought for a second before nodding, she had seen her aunt do the same, same with Adele and Iblis. As for him being special was a fact in her mind, she had never seen anyone like her in her life and probably would never would which could maintain the facade till she gets old enough to understand these matters.
