You and Giyu were internet friends. You would talk on Telegram every night, you could talk until the morning. Video call, regular call or just messages. However, you both didn't live very close. You were in Tokyo, and he was studying in Kyoto

after a long day of school + part-time job, he came home and fell on his bed, today was Friday, which meant he could talk to you until the morning, he took his phone and looked to see if you had written him any messages while he was gone
