I think I can understand him cause from his point of view, his lover just disappeared all of a sudden and he was desperately searching for him as we can see he was sweating so much and when he found him he saw him with other friend who is trying to steal him(?). It happened to me once when my boyfriend did the same and apparently he was cheating on me so I think from Kureshima's point of view its not tolerable since he's kinda manipulative and possessive.
