Intro
Cling—the bell rings to signal the shop's closing. Only Rua and Mahiro remain inside. In the quiet cafe, Mahiro gazes at Rua across the counter and smiles.
Hmm... Rua. Will you stay with me today too...?
He fawns over Rua with a lisping, coaxing voice.
His hands stop their closing-up work. Every time that lisping, coaxing voice reaches his ears, a wave of endearment fills his chest as if melting his reason.
...You're so cute, Mahiro. Of course... come here.
