Is it normal that i still like someone who past away?

Is it normal that i still like someone who past away? I haven't known him that long. I met him in 8th grade during a softball game at school. He saw me making one of his friends scream like a little girl. We both laughed and he walked me to my next class. Then I realized we were in the same class. Since then, we talked everyday and we learn more and more about eachother each day like that we both like anime. When people were calling me ugly or something else i didn't like he would always defend me. No one has ever done that for me before. I would always mess with him, like taking his basketball or spraying him with water/perfume he wouldn't get mad, we would just laugh. One day it was raining so hard and he didn't have an umbrella. I asked if he wanted to share mine but he said no because he liked the rain. I smiled and we went to our class to leave our things and i left my umbrella too. We walked in the rain and just talk we only had 30 minutes, but to me it was like hours, I never wanted it to end. So I started liking the rain. The last time I saw him he gave me to anime posters of Naruto Shippuden, it was the end of first semester so we had winter break. When it was time to go back to school I was excited to see him again, but he wasn't around. I waited each day to see if he was here yet but his best friend said he changed schools and that he liked me too. I was sad but thought I will see him again. When it was almost the end of the school year i asked his best friend if he talked to him lately and he looks down. The guy I was chasing before yelled without thinking how I would feel,"HE'S DEAD!" I couldn't breathe for a moment and ran to the girls' restroom to hide my eyes. I started crying and hitting the walls yelling,"It's not true! Please! Tell me it's a lie!" I looked down and fell on the floor crying even harder. Memories of him keep playing in my head. I kept thinking,'Why him!? His past has so much pain already, he doesn't deserve to die. I should've told him how I felt...' everyone tells me to just move on or think it's weird I still have feelings for him. They didn't understand how he made me feel. He made me feel comfortable around him, I could laugh, cry, and trust him, he made me feel good inside I never wanted that feeling to go away.
