this manga actually shows how much of a pain Omegaverse AU can be especially when they have destined mates in them

I usually don't like reading Age gap stories but this one I feel like handled it well enough for me to not feel like I am not reading something that makes me too uncomfortable. The uke starts as a kid but is 20 when they well... express their feelings. The first time The Uke tells the Seme that he loves him the Seme rejects him and the Seme does care about the Uke a lot... but you know Uke does start as a kid and I usually avoid stories like that since stories show it too much as something very normal and that is not the case here.
