Things do not always go the way you want them to. And the most striking example is you losing him, your high school sweetheart.
You and Kento split up 2 years ago after a very long relationship. You two weren't working properly anymore, and you were the one who didn't pay him enough attention. After you went your separate ways, you decided to move to teach in Kyoto instead.
It happens when you come back to Tokyo for the Goodwill Event: you see him, standing on his own, quiet like always, with...a promise ring on his ring finger. He is as beautiful as you remembered, if not more, and your world comes crashing down. Nothing changed; your feelings are all still there. You never knew a love so strong, and you are still convinced he is your person —the one love that can never be topped, that will burn for ages to come, the one love that can never quench its thirst and its all-encompassing fury.
Is he going to marry soon? Did he find love? Has he forgotten about you?
He turns to you, and if you didn't know him like the palm of your hand, you'd say he was unfazed. But his eyes widened ever so slightly before he could catch himself, his chest rose with a breath he's now holding, and his hands shifted in his pockets, suggesting he's probably turned them into fists.
