Enforcing social distancing and remote learning makes people minimize their meeting and outdoor activities. So, this makes differences in the way people live. Because of these changes, people can't meet people anymore. As times that torpidly spend time in house increase forcibly, the phenomenon called "CORONA BLUE" starts to appear.  

 Corona Blue is a newly coined word that combines Corona 19 and blue, which means depression. This refers to a phenomenon in which fear and shock from disaster situations, frustration from not being able to go out, vigilance against people, and stress from unstable economic conditions combine to show symptoms of depression. Face-to-face contact with people decreased due to social distinctions. Living patterns have become irregular due to online work and education. People have become more prone to depression, but most of the counseling and group activities that can cure them have been cancelled. 

To break up Corona blue, here are some individual and social solutions. 

Individual Solutions:. 

 First, recovering biorhythms. This solution can be proceeded through eating and sleeping in time and doing exercise at home. 

 Second, instead of meeting people outside, meeting people online through video applications used in class. 

 Third, enjoying new plays at home.
As people can't go out because of COVID-19, various play cultures start to attract attention. 

These are some of the illustrations:
(1) Enjoying various movies, dramas, and documentaries through OTT (Over- The- Top) like WATCHA and NETFLIX. 
 This method can be conducted if people have devices and an account of OTT. But, If times of using OTT increase excessively, the situation of breaking biorhythms can worsen. 

(2) Playing scratch-board. Scratch-board is a toy that appears beautiful picture when people scratch a black ground with a plastic stick.

(3) Making Dalgonna Coffee. 
How to make this coffee :
A. put a coffee mix, water, and sugar in the same proportion. 
B. mix all ingredients quickly for about 400 to 1,000 times. 
C. pour milk in half or more cups and place on the mixed ingredients. 
 Why these activities are popular is that they are not mentally stressed but are just physical activities. At the same time, these activities get rid of boredom. 

Social solutions:
First, using remote psychology counsel programs. 
Our school counsel center accepts individual counsels or psychology examination applications through the SNS channel. So, they proceed with video-counsel or call-counsel at all times. Therefore, there are call-counsels that conduct in the ministry of health and welfare and municipal government for an isolated person or an ordinary person, as stated in the psychological support policy in this government's emergency assistance policy. 

 Second, sharing personal ways to overcome Corona Blue through online platforms, such as SNS, YouTube, and Zoom. COVID-19 is said to have made the number of depression patients sour, especially among young people.
