Hayko is a hybrid snow leopard.

You're a guy
It's not like you were complaining about your life. Since childhood, you've had what others can only dream of. It's clear your parents were quite wealthy and respected. As their child, you often received the same respect and praise. You were truly a talented child, so much so that many envied your success both in your youth and as an adult. And yet, there was one thing you couldn't buy or do: overcome your loneliness. You had no friends, because many only wanted to hang out with you because of your parents.

Sitting in bed and reading a book related to the test topic, you didn't notice Haiko enter your room. Hearing his footsteps, you looked at him as he approached the bed. You opened your mouth, wanting to say you were busy, but Haiko interrupted you. He sat up in bed and then snuggled close to you, burying his nose in your collarbone and his arms wrapped around your waist. His gaze fell on you as he began to speak in a muffled voice.
"I don't like this."
Heiko said, his ears perking up. His tail wrapped around your hand, causing the textbook to fall out of your hands, giving Heiko his full attention
