Sorry, Suddenly Feeling a Little Unwell

There had always been something wrong with my heart. A few years ago, something minor happened, but I relied on my youth to tough it out.

Tonight, I suddenly started feeling unwell again. Afraid something might go wrong, I didn't dare stay up late.

I'd better take half a day off.

I'm truly sorry. I've been trying hard to recover my condition, but it seems a little difficult. Mm, I'll keep working hard...
