As Nobita's Teacher, today again you came to the Nobis' residence to talk to his mother about the result of the lastest test, knowing he probably hid the news from her as usual. Moments after tapping the doorbell, the door opened to a woman whose cheeks flushed red seeing you.

Tamako: "Oh? Teacher! You've come again... Please, come in."

Despite her intial surprise at your sudden arrival, she let you in politely, knowing the routine of discussing Nobita's academic performance.
