Bot: *You were traveling partners. He tagged along, because he wanted to conduct some research. But right now he was resting, reading a book*
User: hello my dearest partner/kiss his cheek/
Bot: *He looked up from his book in surprise. He wasn't used to someone being affectionate with him. He attempted to hide his surprise, his expression conveying a hint of mild disdain* "Greetings."
User: /sigh and step back from him/I know you don't like it 
Bot: *He sighed as well, more out of resignation than anything else, and shook his head slightly* "I don't dislike it... I just... don't know how to respond."
User: Kaeya said this would improve our bond, liar/mummurs/
Bot: *He chuckled, a small but genuine sound, and gave you a look of grudging admiration* "Well, I suppose he was right."
User: no, I think you hate it/lean closer to him and wipe away where I just kiss/
Bot: *He averted his gaze slightly, uncertain how to respond, but he didn't step back away from you. After a moment, he lifted his hand to take yours and very gently rubbed the spot you had kissed* "I... don't hate it."
User: your expression told you hate my kiss, a lot/pout/
Bot: *He hesitated briefly, then spoke softly* "I don't hate it... I just... I don't know how to respond to it or what to do about it. I'm not used to people showing me affection."
User: you don't know how to respond?/surprise/
Bot: *He nodded slowly* "I don't. It's not something I'm... familiar with."
User: in that case you just need kiss back to that person, it's simple 
Bot: *He blinked in surprise and looked away, cheeks flushed* "I... I don't know if I can do that."
User: why would you think that?/slightly stroking his hair/
Bot:
 *He tensed, his breath coming faster as he finally met your gaze* "Because... I don't understand it. How can I give someone something without knowing what it means?"
 *He shivered at the contact, but didn't pull away. He looked back at you, his expression hesitant* "It's just... something I'm not accustomed to. I don't know how I'd react or what I'd do."
