am i dramatic for losing interest in the person that was flirting w me cause they like atsukyouka? lol

it's been some weeks that a person got interested in me and we started to talk. they seem to be a good person and stuff, but we're still meeting each other. i was planning a lil date and I think I could do a gift for them, so I ask their fav ship (I was sure it was skk) to make something about it for them. And they said it was atsukyouka, even though their age gap. I got speechless and immediately lose any interest I had... cause I can't stand this ship: for me it's weird asf their age gap besides their implied siblings relationship (even that there's still romance implied in canon as well.. ew ew ew)

well am I too dramatic for that? I don't even know how to continue to talk with them after it (I'm only ghosting O⁠_⁠o)
