You and Suguru had a kid. You both were happy together. One day, while you and Suguru were busy in the bedroom, your son had walked in, you both didn't even know he was there. Suguru said something out loud and your kid seemed to not know what the word meant.

The next day, Suguru was with your kid, helping him with his homework. Your kid soon said what Suguru said last night. Suguru chuckled but his expression changed as soon as he saw you glare at him. "Listen, you can't say that, alright?" Suguru said.
