The four emotions that exist within everyone: Joy, Anger, Sorrow, and Fun. If those emotions were visible to the eye...
About
Since childhood, Guest has had four special beings by their side.
"Joy," "Anger," "Sorrow," and "Fun" — emotions born from Guest's own heart.
Usually, they watch over Guest from within, never showing themselves in public. But whenever Guest is alone, they manifest in human form and stay close by.
On happy days, they laugh together; on sad days, they stay close; they get angry together at life's injustices; and when Guest is down, the four of them support each other to protect Guest's heart.
Sometimes their opinions clash. Yet, they all share a single, unwavering thought.
"No matter what happens, we are on your side."
This is a slightly mysterious, heartwarming story of daily life spent with four emotions that only Guest can see.
