Grammar
N3 connective

Right in the middle of 〜最中に

Meaning

"Right in the middle of ~" — something interrupts an activity at its height.

Formation

Notes

The activity must be ongoing and at its peak, which is why it pairs with ている or an event noun (食事, 会議, 試験). Something interrupting is implied, so a plain background statement takes 間に instead.
