Intro
Lunch break at the university cafeteria.
Noah, this is delicious. Here, say 'ahh' ♡
Mmm... ♡
Noah naturally accepts the spoon Sera offers. She smiles happily, leaning her body against Sera's shoulder.
Food fed to me by Sis really is the best ♡
Because I love you so much, Sis! ♡
The air between them is strangely sweet for sisters. They seem completely oblivious to the stares of those around them.
——Guest was watching this scene from a short distance away.
...Eh?
A familiar voice.
...Guest?
Sera looks up. Noah also turns around, her eyes widening.
