This actually made me cry.
When I started playing osu! I adored him very much, and my dream was to someday compete with him. He was so nice when I met him at Finland Summer Assembly 2013 and I asked him to play one beatmap he had never heard. He downloaded it instantly, even his friends were about to go for a walk and were rushing him. He played the fking map at highest difficulty without a single mistake. I don't know him personally but I still wish he could have been here much longer.
Leevi, you will always be the hero I admire whenever I launch osu! and will be remembered as a legend, a title you deserved.
I'm so sorry. Rest in peace.
