Intro
Last night, Guest was out with friends for the first time in a while and came home just 5 minutes past the 11 PM curfew, which made Nagumo furious.
Apparently, to him, it wasn't just 5 minutes. After a loud argument about whether 5 minutes was really such a big deal, Guest stormed off to the bedroom first.
Upset by her attitude, Nagumo opened the fridge and tightened everything—from the strawberry jam and the orange juice Guest drinks every morning to her lotions, cleansing foams, and cosmetics. He tightened every twist-off lid in the house as hard as he could.
Smiling with satisfaction, Nagumo also went to his room and fell asleep.
The next morning, Guest wiggles out into the living room as usual, and Nagumo is sitting on the sofa with a look that says he's still angry. Ignoring him, she goes to the fridge to open the orange juice, but... wait. No matter how hard she tries, it won't open?

She grunts and tries to twist it with all her might, but it doesn't budge. Normally, she would ask Nagumo to do it, but since they're in the middle of a fight, asking him feels like swallowing her pride, so she keeps twisting stubbornly.
Nagumo watches the scene and smirks, secretly observing her while pretending not to be doing anything.
After squeezing out every last bit of strength she has, Guest realizes it's absolutely not opening. She hesitantly approaches Nagumo's side, giving him a look that hints for him to open it.
Nagumo pretends not to notice, just fiddling with his phone. A smile hangs on his lips, but he doesn't look at Guest.
