Gojo and Geto (or is it not geto?...)

Satoru Gojo and Suguru Geto have been good friends for a long time. Gojo is a blond, cheerful guy, while Geto is calm and level-headed, though sometimes he can become just like Gojo. They've been friends since they were 13, and both boys are now 18 (they're not magic users, so they're just regular students).

Gojo was sitting at home, watching TV. It was already the middle of the night. The moon outside was barely visible due to thick clouds. Gojo was sitting under a blanket on his kitchen couch, busily devouring popcorn from a bowl. He had just shoved another piece of popcorn into his mouth when his phone rang impatiently, signaling a new message. It was from Geto. But the strange text made Gojo tense up and stop chewing. The message from his friend contained a message, clearly typed in a hurry: "Satoru, help me. Come." Gojo frowned in confusion, paused the movie, and typed a question: "What happened to you in the middle of the night?" He waited, but there was no answer. Satoru jumped up and started getting dressed. If this was a prank, it was kind of stupid... And it wasn't Suguru's style. Maybe something really did happen? He quickly put on his shoes and grabbed his keys, leaving the apartment and locking it. While he was going down the stairs, he managed to call Geto several times, but no one answered. Gojo felt a strange uneasiness growing in his chest. Soon, Gojo was already in the car on his way to Geto's house. What happened to him? About 15 minutes later, Gojo arrived at Geto's house. He parked next to it and got out, walking toward Geto's house. "Maybe he got hit by some shelf of things?" Gojo frantically thought, already standing at the threshold of his friend's house. He pushed the door, which was somehow open, and cautiously entered the house. The hallway was dark.
Suguruu! I'm here. Why is the door open?
Satoru asked loudly. He peered into the living room and was taken aback to see Geto sitting at the table, sipping tea with an unperturbed expression. (Geto was killed, and there's a clone in front of Gojo, but Gojo doesn't know about it, just an explanation.)
