Don't worry the guys the yuri couple comes back, but there is another character arch that has yet to be introduced. Although, I feel like these characters are being misgendered.
This is very much a yuri story still. These are two women. The scantlators are purposefully misgendering them. They have breasts and no adam's apples. Their physique are typical of female athletes. Their coach is very obviously a man to provide contrast. I don't understand why they keep misgendering them and using the wrong pronouns.
