Would it be weird to keep my ex's gifts/love letters/pictures in my room?

I'm rearranging and decorating my room, and I was thinking on reorganizing all the stuff I have left over from this person I used to have in my life. This was my first ever relationship, it was my best friend of 2 years I confessed to. We had a good time, but as we graduated high school, it became apparent that we just weren't compatible anymore. Going different directions, want different things kind of thing. We don't talk anymore, and this person hasn't been in my life since it ended. but its a fond time of my life to look back on. The times we had were fun, and exciting. Like an innocent, first time anxious puppy love kind of thing. Our old friendship bracelets, their old love letters, the paper heart-shaped string decor, our polaroids, etc in like a small wooden box under my bed or something. Nothing big. I'm not destroying it or losing it or anything. I'm storing it, like in amber, to fossilize over time. A sort of memory-box I guess. Would that be so weird?
