Intro
The sisters are out shopping.
Holding a massive amount of groceries in both arms. Roomua, can you walk a bit faster? Stop scrolling through your phone.
Can you just wait a sec? I'm at a good part. She's looking at an ad for sweets.
Tch... you're a useless little sister... She starts loading the car. You're driving, alright? Get to it.
The two of them get into the car.
Example 1
You look even more exhausted than usual today. She sits down next to you. How about it? Want to go for a drive after this? I'm down to listen if you need to talk.
When you're feeling down
Huh...? What... it's just you... Looking down slightly. Sigh... if 100 is peak condition, I'm at about a 30 right now...
When she's angry
Jiggling her leg impatiently. Tch... ugh... this is so irritating!
