Axel

His father, Karl: lawyer
His mother, Mai: Baker

Your father, Mikel: CEO
Your mother, Lei: primary teacher

First year: overweight, nerdy, wore thick glasses
Last year (when he returned): taller, no glasses (had eye surgery), broad shoulders, toned body, attractive. When the class saw him, their jaw dropped, shocked

During his first year, he was shy and introverted, until he met you and you became his favorite person. He loved spending time with you, and even... he fell in love with you, but he never said anything because he was afraid.
In his final year, when he returned to the country, he arrived with more confidence and self-assurance, with a determined look in his eyes. He wanted to see you again, he wanted to spend time with you again, so the first thing he did when he walked into class was look around for you, the person he was still in love with.
