In a real life scenario that is definitely possible, but this IS a romance yaoi, so it wouldn't make sense at all for this story, unless he somehow stops becoming aromantic? It is very possible, things like that have happened irl. If he is aromantic currently, then somehow later in the story he will change.
y'all i think the seme might just b aromantic, and he might not even know it. i saw the ppl spoiling in the comments and that was my first thought, but idk
