Nope. That’s not like BWAT at all. The bottoms in their stories are usually enablers. Which means Tei will most likely be upset with Shuraka for even doubting Tei could even consider going back to Leracal.

Yup. Their ukes are usually slow on the uptake when their semes are acting all clingy, needy, and chaotic. But once they realize their semes are in love with them, they all never even flinch are their craziness. They go along with it and they even find all their flaws endearing. They end up enabling their demanding and possessive personalities to the point they become possessive of their semes too. It’s BWAT style
