I'm so looking forward to meeting Rui's older sister and see nii-sans reaction. I was about to write MC but wouldn't that be Maria? He used to be the clear MC in the beginning but it's shifting to her
I know this is all about Yusuke(Nii-san) and Maria and their relationship, but I really want to see more of Yusuke and Rui. For some reason I really think they look good together... but maybe that's just me.
