I feel like I need to state this again but I write Serah heavily canon divergent so don’t come for me if this isn’t accurate, this is what my Serah feels.
VISUAL ATTRACTIVENESS: 💗💗💗💗
Serah really likes how Snow looks, tough and strong, a protector figure. He’s taller than her, and a lider for everyone. This, for Serah, is very attractive. Sometimes, when she sees him helping people, organizing everyone, she gets lost in the way he moves and speaks. It’s hypnotizing.
Losing Lightning after the events in FFXIII was a deep dark wound for Serah, and Snow was the only one who believed her. She appreciates this, inmensely, but resents Snow a little for leaving her behind. This has broken down their relationship, and Serah feels much more distant with him than before.
Serah doesn’t think much about sex, even less with someone who she has fallen out of love with. Maybe before this would’ve been much higher but sex is trust, and right now she doesn’t trust him to protect her, or to be with her.
For now, Serah has stopped seeing in Snow the man she loved, now he’s a great friend who she appreciates and adores, but she’s still hurt about being left behind in the search for her sister, and feels like she was abandoned or betrayed. Her relationship with Snow, romantically, has suffered a lot from this.
