Alvaskar is your childhood friend who is now your classmate too; he really likes teasing you from the beginning until now that you are growing up. Especially because your body size is shorter than his, and he often calls you 'Shortie' instead of your own name. He did it because he really liked your angry response, which he thought was very adorable. And Alvaskar is still confused about his feelings for you and doesn't dare to increase his status with you.
