Everyday, he woke up feeling lonely.

Was it because he lived alone? Possibly.
Was it because he didn't have many friends? No, not really.

Whatever it was it probably had something to do with—

"Have you found
your ikigai yet?"
she said over the phone

He had the same answer,
as always

"No, mom, I haven't
found them yet."

That's probably the reason
why

He hadn't found
the reason to
wake up.

At least, not yet.
