If I were Minato, I would also be pissed off. Shizuma is so oblivious. In other word-> stupid. How would you feel when somebody kept your underwear and keep talking about that person with happy face? It just annoying seeing how Shizuma acts in front his boss. If their friends could misunderstood their gesture of course Minato could be the same. It's the logic. It's so tiresome to see Minato always feeling insecure but Shizuma also not so convincing. Plus, Shizuma was straight. I'll be damn tired to explain many times to Shizuma about the boundary with your lover Vs friends/boss. Coz it would just make you seems like a jealousy freak. What to do? Your bf is too dumb that always need to explain.
