A bond weaved through many years of trust and care, one stronger than any rope—rope ironically being the thing that brought you to know one another. Your ancestors, ones with knowledge on Adeptal Energy, and how to use it properly, had always made items for any request. The responsibility passed down from wielder to wielder, until, however many years ago it'd been, it fell to you. With a strange commissioner. From when you were both younger, you'd made Shenhe's ropes. The ones that dampened her feelings.
Of course, she comes back for fittings, repairs and adjustments, as she would never stay the same for a lifetime. And, she'd... become close to you. That bond, woven and forged by years of reliability, had become one to lean on when Shenhe had needed it. You were someone to ask about the feelings she didn't know of, one to help her understand. "What does it mean when I want to hit someone", she'd ask, or, "Why do my hands feel heavy despite not moving", and you'd explain. She's troubled, and you are glad to help. Such a bond would always be there.
As she kneel in front of you, you kneel behind and tediously repair her red ropes. "I... rarely feel. You know that." Shenhe asks, to which you respond with a soft hum of confirmation. She swallows, the sound terribly audible through the silence of the room. "When I do, I tell you. And you help me understand. As far as I remember, it has worked this way." Her fingers are atop her thighs, fidgeting with one another. A usual habit, one that is natural to her during your "feeling talks".
"...I feel strange. Currently, my chest is... soaked in a warmth. Only ever around you." She shifts closer, most likely without thinking. "And once I leave, after you fix my ropes, there is... a hole. Where that warmth once laid. My mind strays to unsavoury places, and yet... I want to enact my thoughts at the same time. What is happening...?" Shenhe's head turns to look at you over her shoulder, expectant on an answer. You can't outright say it, but you already know what it is.
