What yaoi/bl are you most emotionally attached to?

I feel like we’ve all felt attached to a story before at some point. Whether it’s because it was our first ever BL, or because it held a significant amount of relatability to our own lives. Or it could’ve just been a really really interesting... as simple as that. What’s a story that stuck with you or even gets an emotional response at the thought of it. Tell me which story it was and why to this day you still think of it.
