Hi. I need help in understanding of what happened at pg 208. Before and at pg 207, I can understand Saki is sad and all but, what happened at the "Gasp" at pg 208?? Dragon-kun and Saki both left as if the MC as fucked them real hard.
So, pardon my lack of understanding here and someone could enlighten me here.?!

EDIT: I got my answer in a later chapter. but lol
