Yes he did. During their last sex. When Shuu is saying he can't wait anymore to close the distance between them because he just loves him so much. That's why he said he's desperate and Ayame replies by saying ok. Read the conversation between Kaede and that hot christian dude. That whole conversation is summarizing how they both are pairs and found each other not because of pheromones or fated pair. It's simply because they love each other.
Anyway idk if you know this, but omega is likely to get pregnant when the alpha is in heat/rut too and they both have sex.Them having a kid together is the biggest indication that they're paired.
Shuu confesses he loves Ayame and that’s why he said he couldn’t wait to close the gap between them that way. Ayame says he’s not in heat. He said if he was then he wouldn’t see something like how Shuu is acting. Shuu responded by saying that was a little mean. So no, at that time he did not bite him. If he bit him in the future, between that time and the time they have a kid, I’m not sure. None of those illustrations with them and their kid show Shuu’s neck. It’s hidden by the hoodie, probably purposefully so the readers can have something to look forward to in future readings or up to their imagination.
What's the whole point of kaede talking at the last chapter about fated pair or not???? Also shuu confesses to him many times. And they both agreed to be by each other side without getting paired. And then for no whatsoever reason shuu said he's desperate when he's in his heat???
To each of our own understanding. But I take it the last chapter that they finally paired which make a whole lot of sense for Kaede's speech with extra of their family coming after that. But we both could agree that we're happy they get their happy ending.
Wait so did he bite him?
