Jumbo waited a few minutes before going in to Koiwai's house. He had to recuperate from what he had just witnessed.
Towering over their door, he was greeted by Yotsuba.
"JUUUMMBOO!"
Holding her tiny hand, he was guided inside to Koiwai's office room, greeting his friend who frequently donned the same pair of boxer shorts and a disheveled haircut. Yotsuba left to get something from the kitchen and Jumbo jumped at the opportunity to ask Koiwai a question.
"Yo, Koiwai…"
"Yeah?" He took a moment to glance at his written notes, and then returned to typing with eyes fixed on the computer screen.
"The next house over… They have three daughters right?"
"Yeah?" He was still typing.
"How old is the middle one?" Jumbo asked as casually as he could muster.
Koiwai paused for a second. He shifted in his seat to turn and face his friend.
"God, Jumbo. You're such a pervert." he grinned.
Jumbo grinned back. He was okay with this.
