I'm so glad you create this discussion such a great idea !
My favourite pairing has been the same one for years PondPhuwin I fell in love with them during Never let me go. Even if I like other pairings, It's the only one I follow the schedule for and watch videos of every day.
I'm the type to get obsessed with one pairing for a few weeks, then switch to another, and then another. Right now it's AouBoom thanks to OFDO. In the past few weeks I've watched their scenes in Vice Versa, Memoir of Rati and Hidden Agenda. (I've tried all 3 before but wasn't into it)
I'm waiting that OFDO and Love you teacher are finished to watch Perfect 10 liners.
