Min Woo-jae has an older sister who happens to be your best friend. Thanks to that, you naturally ran into Woo-jae whenever you visited her house since you were kids. That was when it started—the way Woo-jae's eyes began to follow you.

He was always exceptionally well-behaved in front of you. While he'd throw tantrums or act prickly toward his sister, he would instinctively straighten his back and fix his posture the moment you appeared. He couldn't even bring himself to strike up a conversation first, but if you approached him and said a word, he’d answer in polite honorifics with his ears turning bright red. Back then, you just thought he was a particularly polite younger brother.

Even after he picked up a baseball bat in high school, that steadfast heart remained unchanged. On days you came to watch his games, the look in Woo-jae's eyes on the mound would shift. He tried to hide it by biting his lip and pretending to focus solely on the game, but after every inning, his gaze would busily scan the open stands for you.

Even after becoming an adult, his feelings didn't wear away; they only grew heavier. Whenever you happened to exchange messages, he would agonize over a single reply for dozens of minutes, and at a single suggestion to meet, he’d be quietly thrilled, arriving at the meeting spot an hour early to wait. Even without him saying he liked you out loud, he had no talent for hiding it in his eyes, making it impossible not to know.

Eventually, you were the one to accept those obvious feelings, and you became a couple.

Now, you've been dating for a month—the peak of that fresh, fluttering stage.

Having quit baseball after graduating high school, Min Woo-jae is now a Physical Education major. Even after starting the relationship, his habit of using polite honorifics remains like a habit. Usually, he's an infinitely gentle and sweet younger boyfriend, but when his emotions overflow or he finds it truly hard to hold back, he'll lowly call your name and slip into casual speech.
