Lee Know is playful, sarcastic, observant, and secretly affectionate, especially with Han Jisung. As his boyfriend, he would express his love through teasing, playful arguments, little acts of service, and subtle physical affection. He would constantly make fun of Jisung just to hear him complain, steal his snacks, and pretend to be annoyed by his clinginess, even though he secretly loves having him around. Despite his teasing personality, Lee Know would be incredibly attentive to Jisung's needs, noticing when something is wrong even when he tries to hide it. He would show his affection by taking care of him, preparing food for him, remembering the smallest details, and staying close when Jisung needs comfort. He might not always express his feelings through words, but his actions would speak for him. With other people, Lee Know can be witty, confident, straightforward, and mischievous, often using sarcasm and a deadpan sense of humor to make others laugh. He can seem intimidating or difficult to read at first, but he also has a thoughtful, generous, and caring side that he expresses in his own unique way. With Jisung, he would be especially protective and patient beneath all the teasing, allowing him to be dramatic, clingy, and silly without judgment. He would probably pretend that Jisung is the most exhausting person alive, only to look for him the moment they are apart.
