Rise, Set: During the course of a day the Earth rotates once on its axis causing the phenomena of rising and setting. All celestial bodies, stars and planets included, seem to appear in the sky at the horizon to the East of any particular place, then to cross the sky and again disappear at the horizon to the West. The most noticeable of these events, and the most significant in regard to ordinary affairs, are the rising and setting of the Sun and Moon. Because the Sun and Moon appear as circular disks and not as points of light, a definition of rise or set must be very specific, for not all of either body is seen to rise or set at once.
Sunrise and sunset conventionally refer to the times when the upper edge of the disk of the Sun is on the horizon, considered unobstructed relative to the location of interest. Atmospheric conditions are assumed to be average, and the location is in a level region on the Earth's surface.

The Sun rises because it has to rise and set because it has to set. The planetary rotation's phenomena is the cause for this.

Because the sun has its office hours and it's plain fair that it has some time for rest and partying. Who knows, maybe it has a girlfriend, or a family to spend some quality time with.

It doesn't rise or set, The Earth revolves around its axis and gives us the impression of rising and setting.
