Change to requiring reserve system

Yesterday I made documents at the office in the morning.

A student came to take lesson in the afternoon.

In the evening, English conversation cafe was going to be held at our cafe.

But any people didn't come, therefore I couldn't open it.

From now on, I will change it requiring reservation system and continue it.

Today I'll work at the office in the morning, then K-pop seminar will be held at our cafe in the evening.
