So what you are saying is that your ex is cheesy.
I am not sure I remember my first ex's (R) scent. I would probably recognize it in an instant, though. I remember other things. The first date, the way we sat in an ice cafe on 14th January, eating icecream, and a child ran to our table and randomly said "Happy New Year!", which made both of us laugh; the first kiss which lasted forever, while there was a photographer bustling around, photographing the city below us; going down from that hill we kissed on, be lighting the way with my crappy mobile; the first few *cough* "intimate dates" in an unobserved corner of the Starbucks on one of the more prominent streets of her town; the first time she snuck me home for a few hours of the night because her mother was coming from work late; me entering and saying "wow, your appartment is pretty!"; me being there again officially, with her mother present, entering and saying "wow, your appartment is pretty!" x); celebrating her sweet 18 in Poland, and the argument I had with her mother; the argument I had with her mother on the last day of the vacation, when I threw a door in the mothers face, sending R into a catatonic state as we continued to argue and both of us backing down as we realized it. The problems we had. Making sure none of my stuff is at her place while she was packing for her next vacation. Breaking up with her via text while she was on that vacation, because I could not continue to pretend being invested in the relations hip for another two weeks, and feeling miserable about it nonetheless. Seeing her again for one last time after that at a convention.
Yes, I remember a few things.
I also remember things about my most recent ex, D, but I should NOT start digging around in my memory now.
