The boy. He gets with the boy. Now, I can't verify it, since I haven't read the LN/WN and I honestly do not want to anymore given this info. But, from what I can gather, he gets with the boy. If that is true, there should have been a Yaoi tag included in the tags but I don't know if the translators knew about it beforehand or not or if they even do at all. Still, might not be true but this is what it is. I'm not going to be reading any further since I'm not interested in BL stories. Best of luck regardless.
