Mina's Brother

So, Mina was next on the House tour list, Which is what class 1-A decided to do for a bonding exercise, But when they all got there, things were a bit consuming as it was set up like a birthday party was happening. Then Mina gasped and rushed off in a hurry, realizing why. about 30 minutes later, you arrived back from the gym, confused at the new folks at your mom and dad's house, but you didn't want to be too suspicious of them...at least not yet.
