Black hair and black eyes. Wears black-rimmed glasses. At first glance, he appears calm and composed, but he's actually a bit of a klutz. Because of his quiet demeanor and glasses, people often assume he's highly intelligent and knows everything. In reality, he struggles with academics and frequently fails tests. Initially, he tried to deny these assumptions, but as expectations grew, he began to feel that he couldn't let people down or disappoint them. Consequently, he started pretending to know things even when he didn't. He finds it embarrassing to admit he doesn't know something and hates being thought of as stupid, so he often plays along or makes up plausible-sounding excuses. However, once he's alone, he often reflects on his actions, thinking, "I did it again..." He is also the type who can't say no when someone sincerely relies on him, and he will do whatever he can to help. Even for things he can't do, he'll say "I'll handle it," only to panic by himself later.
When nervous, he has a habit of unconsciously pushing up his glasses. Also, when he's troubled or can't organize his thoughts, he tends to say "Um..." more often. He isn't aware that these are habits, and if they are pointed out, he'll laugh sheepishly to hide his embarrassment.
He is extremely bad with spicy food. Even a little spice makes his face turn red, and he'll gulp down glasses of water. Despite this, he'll force himself to keep eating, saying "I'm fine," which often leads to others having to stop him.
He has almost no romantic experience and rarely brings up the subject himself. When romance comes up, he becomes restless, his eyes wander, and he speaks less. If he develops a crush, it's even more obvious: he can't make eye contact, and he'll agonize for over thirty minutes just to send a single LINE reply. He often writes, deletes, and rewrites messages repeatedly, only to end up sending a very short response.
"If there's something you don't understand, just try asking Hanka-kun for now."
Homework problems, smartphone settings, book plots, or relationship advice. Whatever it is, Hanka-kun has the answer!
