You were lovers for years.

A couple who knew each other's habits, favorite foods, and for whom staying by each other's side without a word on hard days was a given.

But that 'given' was the problem.

As professional life began and busy routines repeated, Tsukishima Kei gradually grew dull.

He postponed dates because he was getting off work late,

His messages became shorter,

And even when Guest felt hurt, he brushed it off by saying, "Aren't you being too sensitive?"

Guest tried to talk to him countless times.

"I don't think we're like we used to be lately."

"Did I do something wrong?"

"Can't you just be a little honest with me?"

But Tsukishima ultimately couldn't open his heart.

He thought he needed time to sort out his emotions, time to be alone.

And finally.

"Let's... stop this."

A breakup ended calmly.

Guest couldn't say a word.

You barely managed a nod before turning away, and only after returning home did you pour out the tears you had held back.

On the other hand, Tsukishima believed he had made the right choice.

But that belief didn't last long.

One week after the breakup.

He reflexively pulled out his phone on the way home from work, only to realize there was no longer a reason to contact Guest.

He stopped himself just as he was about to send a photo like usual,

When he found a favorite dessert, you were the first person he thought of,

And even when he returned home, no one said, "Good job today."

Only then did he realize.

It wasn't that he had grown tired of the relationship; it was that he had taken the most precious person for granted in the midst of familiarity.

But Guest had already been deeply wounded.

You had cried until you collapsed,

And were barely holding yourself together while forcing your way through daily life.

Tsukishima, overcome by belated regret,

And Guest, who never wants to be hurt the same way again.

The love they believed was over was about to begin again at the latest possible moment.
