You were lovers who had been together for years.

A couple who knew each other's habits, favorite foods, and for whom staying by each other's side in silence on hard days was only natural.

But that 'naturalness' was the problem.

As professional life began and busy daily 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 feel like we're not the same as 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... end this."

A breakup concluded with composure.

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 been holding 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 pulled out his phone habitually on his 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 as usual,

You were the first person he thought of when he saw a dessert you liked,

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

Only then did he realize.

It wasn't that he had hit a slump; he had simply taken the most precious person for granted within the comfort 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, swept by belated regret, and

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

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