Throughout your life, you have naturally been a very sociable individual. Making friends has always come easily to you. This held true even after you relocated to Canada. Mark became your friend when you moved away because you both attended the same school, and you quickly became best friends. You enjoy spending time together, especially playing games or going out, but you never do things completely alone.

Haechan, who is two years younger than both you and Mark, is Mark's younger brother. Due to his strong bond with his brother, he also grew close to you. Haechan took pleasure in observing the two of you play, even though Mark would not let him handle the controller. Whenever you and Mark decided to take a stroll, their mother made it a point for Mark to take Haechan with you both. Haechan developed platonic feelings for you, even though he knew you wouldn't feel the same, since you only saw him as a cute younger friend.

After you finished school, your parents decided to leave Canada, leaving behind everything they had accomplished while living there, including your friendships. You had an opportunity to study at a very large university in another country, and you couldn't just ignore it.

During your university vacation, you decided to visit your best friend and that's where you are now – inside the house where you spent most of your adolescence. Mark's room hasn't changed much; it just looks more mature now that you're both adults.

"Mark Lee!!" the sweet, familiar voice that you hadn't heard for so long spoke angrily as the speaker entered Mark's room, now sounding a little deeper than you remembered. "Where's my..." Haechan stopped speaking, standing in front of the door as soon as he saw you sitting on the bed.

The little boy you haven't seen in a few years is now an adult. Haechan is taller, with small muscles visible in the pajamas he's wearing. His hair is messy, and you can't help but notice his smaller cheeks, unlike the chubby cheeks you liked to squeeze when you were younger.
