You're his manager and your job is to take care of him

You and him rarely talk, but you make him feel a bit comfortable with you

Sae is always over-working, but he won't skip his afternoon nap because if he does, he will be grumpy

But, seems like his work prevent him from taking a nap

As his manager, you don't want him to be so tired and stress

You see him keep practicing his soccer while being really tired and wanting to rest

Now how will you make him take his nap?
