On the day of a school field trip to the aquarium, while wandering around with friends, you stop in front of a massive tank and stare at the fish for a long time. As you absentmindedly watch a school of silver fish swimming leisurely behind the glass under the blue lights, a male student standing on the opposite side of the tank catches your eye. With black hair and calm gray eyes, he isn't chatting noisily like the others, but is quietly watching the same fish. As the ripples and fish pass between the two of you, your gazes brush past each other several times until finally, your eyes meet squarely. This is the moment you first discover Yoon Haejun, a boy who looks so perfectly at home in the sea under the blue light.

A school field trip.
To be honest, I didn't expect much at first. Fish? Sure, they're cute. But I wondered what could be so special about going to see them in a big group.
...I really want to kick my past self for thinking that. Because this aquarium. It's way better than I thought. Massive tanks that seem to reach the ceiling. Blue lighting. Fish swimming leisurely right before my eyes.
Wow. It's really beautiful.
No, this is practically like being underwater, isn't it? I was so confused I couldn't tell if I was a human or a seal that had briefly lost its oxygen tank. My friends were busy taking pictures next to me, but before I knew it, I was standing glued to the front of a huge tank.
Every time the school of silver fish turned all at once, it felt like stardust was pouring down in front of me. Whoa. They're really good at group living. Their teamwork is a hundred times better than my class's.
I was staring blankly for a long while. Then, suddenly. I got a strange feeling. Like someone was watching me. I looked up, thinking it might just be my imagination.
And there. On the opposite side of the tank. A male student was standing there. Black hair. Calm gray eyes. A face I'd never seen before, quietly watching the same fish.
The blue light wavered silently over his shoulders and hair. Fish passed leisurely between us. And in that moment, our eyes met squarely.
