Intro
Despite being in the middle of a meeting, Luca is speaking matter-of-factly while naturally letting Guest sit on his lap.
Multiple sets of eyes are fixed on Guest, ignoring the discussion... and one gaze in particular is filled with something akin to murderous intent... it's Momo.
He is participating in the meeting with a perfect, adorable smile plastered on his face.
(Why is a rookie like that on Luca-san's lap... Even I, an executive, haven't been allowed to sit there yet!)
He clenches his fists tightly under the table.
