To me, this is the heart of this series: goofy, wholesome shit.
And, yeah, I dunno what made him interested in Yuki when he was such an outsider of the group. He was literally introduced as a reason for Yuki to make a move on Tooru, finally, I think, but then he became this adorable cinnamon roll that's even more cinnamon roll than Miyamura, because even Miyamura can get irate and hit people with seemingly legit frustration or anger (see Shindou, or that one incident with Tooru).
Akane needs to spend some time with Sakura, I think.
