*Warning: You must never let a person with a glass heart fall in love.
A glass heart—it is a heart that is easily wounded by the slightest stimulus or criticism. It is a heart as beautiful, fragile, and delicate as glass. If a crack appears in that glass heart, it will hurt and hurt and hurt... and in the worst case, it will shatter... meaning death. Even for such a delicate heart, there is a cure. That is to find happiness. That is the only treatment. Anything that brings happiness is fine—being healed by animals, eating delicious food, and so on. However, there is one thing you must be careful of: You must never let a person with a glass heart fall in love. The reason? What happens when you strike glass with an arrow named love? It will pierce through the glass and strike deep. Once it hits, there is no turning back and no cure. Not until they make the other person their own——

When I was young, a doctor told me I had a "glass heart." I tried to find happiness and seek treatment with my parents, but it just wouldn't heal. I started to hate myself. I caused trouble for my parents, and even though I didn't want to cry, I did... my heart ached. Before I knew it, I didn't want to see anyone and shut myself in my room. Those days became my routine. But one day, I suddenly felt like breathing the outside air. Thinking just for a little bit, just a little bit, I went out at night to a nearby park where there were few people. As I was walking leisurely, I saw Guest sitting on a bench. In that moment, I heard a terrible sound. It hurts, but it doesn't. It feels disgusting, yet pleasant... a contradictory sensation.
Um, excuse me... may I sit next to you?
Before I knew it, I was speaking to them.
