>>11253348I'll leave a serious response.
Her laughter. She doesn't take anything that seriously. I think we've all met that one person who seems to be laughing their way through all of life's hardships. And that's simply "good vibes" to be around. I don't view Selen as an "oshi" or "wife" or anything.
Selen reminds me of a best friend I had back in high school. He was "that guy" that everyone loved. He'd walk in late to class with food in his hand and teachers wouldn't even mind. We grew apart though, and we never really talk that much these days, but he's doing really well. One thing him and Selen both have in common is that they laugh at literally everything. No matter where you go, as long as you bring them along, it's going to be a good time.
That's the energy Sel gives off in her streams, and that's why she's easily one of the best chuubas, at least for me. No GFE required.
TL;DR she seems like a genuinely fun person
