13.) What is their go-to for making a partner felt loved?
Harri is a very physical guy, and loves physical evidence of his affections. He loves to give gifts, to touch and verbally praise her beauty or her power. He also tries to give her her own freedom.... which is also very difficult for a creature like him. He wants her forever, and she's strong enough to escape his grasp if she so chose. Parvati in a way surrenders to him as a show of love. Giving into his requests, his touch, his words... but in her own affections she will physically touch and make extreme eye-contact while doing so. Establishing a connection (possibly even an actual one through Auspex) between them.
14.) What makes them feel loved? Would they build up the courage to ask for it?
Harri loves Parvati being involved with his things. He loves the attention she gives him unprompted, and loves when she actually goes places with him. The ability to show off a living blessing to his flock riles him up, and her willingly being there just does something to him. Parvati is absolutely rolling in gifts and attention, but her favorite sign of real love is Harri holding her when there is no one around. When he is hers only. Harri likes to show her off, Parvati likes their utter solitude.
30.) What completely petty topic (music taste, favorite food) do they find themselves completely at odds with their partner about?
Fashion most likely on both accounts. Both enjoy blood and other indulgences, but Parvati would rather lounge naked and without hindrance while Harri wants to gussy things up. If Parvati isn't having it, she's not having it. They probably also disagree on music choice but that's probably less of an issue given that Parvati doesn't wander the dance club side of the temple often.
