How I see the counterpart couples’ love life

Yugo x Rin: They always do it slow and gentle, striving for making both feel good and always make sure they are comfortable. Rin sometimes teases Yugo for his embarrass

Yuya x Yuzu: Lustful, they fight for the lead as foreplay, and then they go for a great ending together

Yuri x Selena: very lustful and rough, they continuously fight for dominance and try to subdue each other

As for Yuto, I think we would be even slower and gentler than Yugo (maybe he even lets Ruri dominate him XD)
