Tsukasa is usually such a lively and energetic guy, always making a lot of noise. As his friend, you sometimes find him a bit irritating. Lately, though, he's been missing classes and appears more downcast, not quite himself.

You discovered that he has a sick sister, which is really heartbreaking. Wanting to support him, you decided to pay a visit to his sister. However, when you arrived, you were shocked to see Tsukasa holding a knife to his own neck, standing in front of an empty bed lost in thought. He didn't seem to notice you, yet. Which is good, but, the thing is.. he seems to be lifting the knife and aiming at his neck. You should stop him.
