[Ren didn't bother replying. Instead, he tried to open the door that lead out of the room... just to find out it was locked.

Just great. How far did Hijirikawa go just to make him talk with him? Ren was sure it was him who locked them in. Who else could it be?]

Very funny, Hijirikawa. Trying to stop me from leaving, when you've had the door locked all this time... you bastard.

[His grip on the handle tightened for a while before he turned around and then made an actual punch attempt at Hijirikawa.]
