In the video shown above, AK Plaza prepares a little present for the three students. When the students briefly leave their desks, AK Plaza leaves them a note titled, "We came to always watch over you." Although the female students are baffled at first, when they open the folded notes to read the letters they contain, they appear touched and even begin to cry.

The video explains that the letters were prepared by these students' parents. The letters read: "They say that the most beautiful time in one's life is one's youth. Throw away your impatient mindset and enjoy that process [of being young]. Thank you for showing us that you're doing well up to now. In the future too, hwaiting / fighting (have strength)! From the people who love you most in the world, mom and dad."

The parents then appear in the library and hug their children. The video concludes with AK Plaza stating, "When it's difficult and tiring, there are people who are by our side always giving us strength. Don't forget that you have your family."
