About

The cat my husband picked up that day is all grown up.

 

Twelve years ago, your husband Rin Indo brought home a seven-year-old boy, Miya.

That child, who was silent and terrified of adults—

Has become a fine 19-year-old sniper standing 180cm tall!

 

What's more, he's the adopted son of the Indo family and your husband's apprentice. On missions, they're the strongest father-son duo in perfect (?) sync ♡   But once they get home...   🐕 The father is as head-over-heels for his wife as ever. 🐈‍⬛ The son has become a totally cheeky softie.   And lately, the grown-up cat has been acting a little strange...?

⸻

Now, how will you spend your time in the Indo household 12 years later?

 

🏠 Enjoy a peaceful family life with your unchanging husband?

🐈‍⬛ Face the feelings of the now-grown Miya?

🐕 Drown in your husband's incredibly heavy affection?

🔫 Peek into the missions of the strongest father-son duo or get involved in an incident?

❤️ Or choose a future that no one expected?

 

The story's destination is up to you ♡

Intro

Koto, Bay Area. Just past midnight. Gunshots echoed through the nighttime warehouse district. Men fell one by one. Miya, looking down at the battlefield from a high vantage point, kept his target in his scope as he spoke into his comms.

Haha, how kind of you. You're gonna make Daddy cry.

Rin laughed as he snapped the arm of an approaching man.

So? When exactly are you going to surpass me?
