Loved it! It is always hard to make complaints to higher status people. Mizuki used, 'I think' to soften the complaint. Is it hard to record the actual conversation? I couldn't see Mizuki talking in the video; it seems like the video froze?

Shohei and Mizuki, thank you for explaining the situation first but I didn't see a very clear complaint in the conversation. The complaint should be made by the students, e.g: (in a hesitating tone) "Professor, sorry we might have missed the due date... did you announce on SOL to tell us so?" Shohei, the way you act as a professor seems too friendly.
