While many students had to deal with the blaring of alarms, from clocks or phones or other devices, their was maybe a handful of students who did not use or did not require such devices.
Suo was amongst this small few, as he was able to take some of the esoteric things he's learned from his uncle, and found practical applications of them. "Every-day Zen" as his uncle called it. It let you get away with doing stuff like having an accurate-to-the-minute biological clock.
It also helped when you wanted to literally spring out of bed, fully alert and ready to take on the world, which is exactly what he does. Years of getting rapped on the head by his uncle for sleeping in has also instilled this sort of discipline in him.
He was showered, dried off, and dressed in no more than thirty minutes; and that left him with nearly an hour to get to school, and pick up breakfast along the way. He would need that time; he's clocked himself before, in years past. It was thirty-five minutes to walk to school on average; more in inclement weather, more or less depending on foot and car traffic.
With his entire day seemingly already planned out in his mind's eye, he set off from the temple, with only a brief wave goodbye to his uncle, who was already preparing himself for his morning meditation. Every step of the way was even, smooth, planned, and saw him slipping and sliding in and around others, following the path of least resistance.
Along the way, he would stop at one of the many vending machines that overpopulated this part of the world. One which proclaimed that a hot, fresh meal was just five minutes away! And sure enough, after the machine had been fed the Yen it demanded, and his selection was made, five minutes would begin to pass, as the braised pork meat was... heated? Reconstituted? He did not know how the machine operated. In fact, this is one of the few times where he did not wish to know. It was relatively cheap, it was fast, filling, and an excellent source of protein.
He spent the time loitering around, and also, getting himself a bottle of water, so as to quench his thirst.
