I think despite the "yaoi" tag someone placed on this, this has been consistently more shounen-ai. I never got a hint that there will ever be any explicit sex. I think the most it'll have is a panel that suggests they slept together (like one where they wake up on the same bed). But even that I'm not sure is guaranteed. Unless the author is one of those that put the sex scene at the very end of the stories, I don't think it's coming.
Honestly I was thinking the same, it would be nice but I'm not going to have my hopes up for it really. The story is still great though like no doubt I've been enjoying this shit fr. Even if it gives implications or not story still fire.
Might be a little fucked up but like......when they gone fuck? I've been waiting for that. Story is amazing though not the first but one BL/yaoi that I'm actually enjoying, and it's not a nothing burger with just sex.
