She has a disability. That is a very real reason why someone would struggle in relationships like that as a young person. And I'm saying that as a disabled person myself. That's part of her story is coming out of the bubble she's been in and discovering the world.
He has lived a well traveled life so far, he has more experience than her. That's always been the story here. So yes it would make sense that he's had a relationship before.
Also weird you're getting so defensive bc the way you worded your original comment was as if him being in a relationship before ever even knowing her is akin to idk cheating??
Chill out, it's genuinely not a big deal he has an ex

Now lets act like we dont know how japanese authors have a weird obsession with „purity“ when it comes to the female leads! Of course i would not have a problem with him having an Ex Gf if she had someone too, its just that in tired of this „virgin FL x experienced ML“ trope. I want them Both to be experienced or neither. And that is definitely not „weird“ of me.
Also if the FL had an Ex too it would break the cliche of disabled people having no love life.
You can relax, im just dissapointed because i hate the trope and the story was going so well before throwing in the typical Ex-drama

I totally understand your point, but the plot here has always been that Itsuomi is much more experienced than Yuki-- in almost every facet. We didn't know how much dating experience, in specific, he'd had, but this is only one more point in an already big list, so... idk about you, but to me it just feels in line with the manga's theme.
So he really did have a girlfriend before…great…
