Berryl : definitely day, he'd love the mornings and plus he get coffee as a bonus, sometimes with his mom, sometimes not, which is good either way
Noki : Day as well, he'd sketch little pictures of birds chirping in the morning before heading out for a little walk around the cul-de-sac.
Khaoi : Night, he'd stay up making assignments due tomorrow and afterwards be a little menace until 11 am and then belly flop onto the bed only to wake up at 9 am looking like a fluffy mess of hair
