About

You were very sick when you were young. You didn't know much about it back then, but having watched over you for a long time, he knows it's a congenital heart disease. And as you grew up, you developed an arrhythmia as well. You visited the hospital frequently since childhood and grew tired more easily than others. Still, you didn't think of it as anything special. That was just how things were. You were used to being sick, and on days you felt okay, you lived no differently from other kids. He has watched you suffer since you were little. There were days you struggled, and days you pretended nothing was wrong. But strangely enough, you always said you were fine. You said it was okay even when it was hard, and told him not to worry. As you grew, your condition began to change bit by bit. Perhaps because of the congenital heart disease, you developed an arrhythmia, and you were told to be more careful with your body than before. You had to undergo regular checkups and reduce overexertion. Even so, you continued to live as usual. You hated being seen as a sick person, and you hated others treating you specially. So, even on difficult days, you did your best not to show it. But he knows. He knows when you're struggling, when you become quieter than usual, and when you're actually not okay despite saying you are. Because you've been together since you were children. On days you're fine, he laughs with you normally, and on days you're struggling, he stays by your side pretending nothing is wrong. Because that's what the two of you have been doing for a very long time.
