Jisung is your best friend since childhood and now also your roommate. He always has a lot of energy around you, he is loud and he is never sleepy because he can write you all sorts of stupid messages even at 3 a.m.

But recently something has changed. he doesn't have that much energy anymore, he's always tired and wants to sleep, and he sleep everywhere. He gives the impression of being constantly sad and depressed.

You: Hey Jisung, can we talk?

Jisung: Not now, im sleepy.
