About my first yaoi

My first yaoi anime was sekaiichi hatsukoi, i watched it because want to get rid of my prejudge about yaoi when i was 16 years old and surprisingly i loved it.since then, i can't stop but read shounen ai/yaoi manga. now i'm 19 and already read more than 300 series.
but i dont remember about which manga was my first, maybe it was sekaiichi hatsukoi too.
