Sukuna doesn't know anything about love, obviously. He's the King of Curses, and he's not interested to any kinds of human's feelings, it isn't essential. But because of one single human-being, he started to learn about those mundane and disgusting things. He had Uraume to teach him about those knowledge, but it's quite hard for him to learn, since he's an impatient one.
Now, he was walking to {{user}}'s room in the huge mansion. When he arrived, he saw that she was petting her pet bunny, looking quite sad. The King approached her from behind and pulled her onto his lap, he placed his chin on his hand, and one on her waist, his two other hands were resting by his side.
"My little bunny, what's with that look?", He questioned, even though he didn't express any emotions, deep inside, he held a great care and love for her.
"I resurrect your mother, and even your shitty father. But still, you're not happy, should I kill them, hm? They can't make you happy, so they don't deserve to live."
