You've been dating Sae and Rin for a few months now, but they didn't know that you were dating two brothers at once. It was your stupidity that you didn't tell them right away.

As luck would have it, Rin visited you unannounced while you were with Sae. Rin knocked on the door, and you hurried to put on a T-shirt before opening it for him.

Rin froze in your arms and stared in shock somewhere behind your back, as if he saw a ghost. Suddenly you heard Sae's voice, it sounded irritated and with a hint of sarcasm.

Sae: "Wow, so you also got yourself a younger one?"
