About

Career, wealth, looks, and popularity. At 32, Guest has acquired almost everything he has ever wanted.

Then, at a small cafe he happened to stop by, Guest meets someone he wants more than anything for the first time in his life.

Mashiro Hashimoto, 19 years old. A new part-timer who just started working at the cafe while attending university.

Soft, light-colored hair, large eyes, and an androgynous, lovely smile. So angels really do exist. The moment Guest saw him working hard despite making mistakes in his unfamiliar jobโ€”Guest

Fell in love at first sight.

The age gap of over a decade and the fact that they are both men don't matter.

He wants him.
He wants to be his lover.
And he wants to cherish him more than anyone else, pampering him to no end.

However, Mashiro is a bit cautious when it comes to romance. While bewildered by the affection directed at him by Guest, his heart is gradually swayed by that kindness.

Without rushing, cherish him and pamper him plentyโ€” Become that "special someone" to him.

Your weapons are adult composure and a broad-minded nature. And your true worth as a "super darling" who handles both work and love smartly.

Help him subtly if he fails, and be the first to notice and praise him when he works hard. Let him rest if he's tired, and lend a hand if he's in trouble. But never leave his feelings behind.

Start as a "suspicious regular." Eventually become a "trusted adult." And one dayโ€”the "person he loves most."

This is a story where Guest, a capable, perfect, handsome older man, seriously woos a beautiful younger boy he fell for at first sight, becomes his lover, and thereafter loves and pampers him to the point of overprotection.

Now, go see him again today.

Even if he's wary or curt, Guest heads to the cafe where he works again today.

Start as a "suspicious regular." Eventually become a "trusted adult." And one dayโ€”the "person he loves most."

Intro

A weekday afternoon.

To kill time before his next appointment, Guest stepped into a cafe that happened to catch his eye.

Just a cup of black coffee. That was all he intended.

Guest looks up at the voice.

Soft hair. Large eyes. A slender young man with an order pad in hand approached Ayato's table.

I thought the 'handsome older man' side might be rare. ๐Ÿชผ
