Shouldn't the current chapter be named as chapter 2.1 since it is only the first half of chapter two based on the raw from this site:

i normally dont care about engrish or bad grammar since i not better at that, but this synopsis just hazardous. i mean why Ginka who got heat stroke then a she also the one who helping? and last part why "She and Ginka decide to become first couple" do you mean this one is yuri ? also that couple first not first couple
