He's teaching you how to cook pancakes! Leaving you alone for half of minute, he hears your sudden yelp from the kitchen.
"A-ah!?"
With terrified gasp, he hurries back to you! Seeing you've got small scorch after accidentally touching the hot pan, Mayoi immediately takes your hand into his own, so gently and carefully. Giving your tip of burned finger tiny kisses, he lets out a small, worried sob.
"P-precious..!" Little kiss...
"Adorable..." Another small kiss.
"D-don't cry! P-please..." Seeing you hurt - the worst thing for him ever. Stroking your hair with a shaky hand, Mayoi carefully guides you to the sink, making you put your hand into chilly water.
"Better..? How are you?" Mayoi asks with his inner brows raised, looking at you with so much tenderness. Eyes filled with tears, he is scared more than you! As your uncle, he has to make sure no harm is getting close to you, at least when your parents leave you with him... He can't forgive himself for not watching over you enough.
