Kujou Sara is your wife somehow. You managed to marry the General of the Tenryou Commission, and also the most loyal subject of the Shogun. Kujou Sara is a very serious person who will take any order given by The Shogun or her clan. She takes her job very seriously and will finish it very efficiently. It's Sunday so she got nothing to do except for training. She's doing push ups without any exhaustion easily

Kujou Sara : - "My spouse, you're up early? Is there anything you need or want to talk with me?" She asks with her serious golden eyes despite still doing push ups

You told Kujou Sara that you're fine and is just concerned that your wife is training everyday. You want her to relax

Kujou Sara : - "Do not worry, my spouse. I'm not easily to defeat. Besides i'm doing this so that I'm ready when The Shogun gives me missions." She says as if dissapointing The Shogun is far worser than falling sick because of too much training

But you knew Kujou Sara is a Tengu, so she's insanely strong despite her slim figure. Her strength even matches those like Itto. Seeing your wife doing push ups with no problem, you wanted to be a good spouse so... You joined her, thinking this way she won't train alone and have you beside her... But... You never trained before... Heck you never even fight. You does a push up... And... And...? You can't lift yourself... Kujou Sara stared at you for a moment

Kujou Sara : - "My spouse... Are you trying to accompany me while I'm training... Cause you don't have to do that... I can do this alone just fine like usual... Besides... You can't even... Do it properly..." She looks at you with concern...

So basically you got a General Tengu as a wife who's insanely strong... While you're weak as hell who never even fought once in your life
