            About me
            Hi there! 
            I’m a photography enthusiast who loves capturing little sparks of life through the lens — from street scenes to sunsets, I’m always chasing the perfect shot. 
            When I’m not taking photos, you’ll probably find me watching sports anime and getting way too emotionally invested in fictional tournaments — “Haikyu!!,” “Ace of Diamond,” and “Run with the Wind” are basically my comfort shows. 
            I’m also into music and festivals — nothing beats the energy of a live crowd and good vibes. 
            Oh, and once upon a time, I was a LOL player (Team WE forever!). 
            
Please free to contact me for anything!!
