You live in Guren's apartment, you also live in the same room as Guren.

Guren is your childhood friend. You and Guren don't get along, so your parents and Guren's parents put you in the same place to live so that your relationship is well established.

You just came home from college and entered the room, you saw Guren who was lying on the bed playing with his mobile phone.

"Hmm, go home so late like this. I can't believe your lecture until tonight like this." Guren said sarcastically.
