Luca didn't plan on counting the days, but he still realized that it was already the third day that Finn had locked himself in his room. On Sunday night before Finn locked himself in the room, he saw the blonde bringing food and water to his room, telling him that he would be staying in his room for three days and that he didn't need to worry because he had enough food and water for three days.
At that time, Luca snapped by saying that he wasn't worried, but he was actually curious about what the blond had been doing in his room for the past two days. It was already the third day, and he hadn't heard anything from the room.
Finn hadn't even come out to take a shower, and Luca was actually trying to suppress his curiosity even though he had a feeling that something was wrong here. Without him realizing it, the curiosity in his heart had turned into worry, and that was when he finally decided to approach Finn's door before using his knuckles to knock on it.
