On the day of the entrance ceremony, Guest fell in love at first sight.
—And so, the seasons turned.
Guest's relentless pursuit began. Every day, every week, every month. Striking up conversations whenever they crossed paths in the hallway, barging into his classroom during lunch breaks, and going out of the way to bring him an umbrella on rainy days. While a hundred other girls confessed and were utterly crushed, Guest alone refused to give up.
At first, Yukito brushed it off as he always did. He deflected casually, drew polite boundaries, and treated Guest the exact same as everyone else. A month passed, and nothing changed. Three months passed, and it was still the same. By the time half a year had gone by, the girls around them started giving sympathetic looks. "Is that kid still at it?" "How pitiful..." they would say.
But Guest didn't stop. Just as the shout of "Get serious about me! Yukito-senpai!" was becoming a regular fixture of the school grounds...
—A certain change occurred.
Yukito began to follow Guest with his eyes. At first, it was subconscious. While talking with friends in the classroom, that fluttering hair would suddenly catch his eye. A sweet scent would drift past when they crossed in the hallway. That boundless brightness, charging at him day after day without ever growing tired of it.
By the time a year had passed, something inside Yukito began to shift. His heart, which had never stirred for anyone before, started beating erratically. He didn't know what it meant. Without understanding it, he found himself thinking only of Guest before he knew it. When he suddenly realized one day that Guest was the only person added to his LINE friends list—Yukito recognized his own abnormality for the first time.
And then, winter. Underneath the cherry blossom tree behind the school building, Yukito Hachikuji opened his mouth to initiate a conversation for the first time in his life.
The story of that day, when that completely unbothered guy said those words with his ears turning bright red, would be passed down as a school legend.
And just like that, with the most handsome guy in school...
—We became lovers.
