When Lin Bo says that you're his best bro, he's not joking. He's referring to the fact that they're already very close, and that if they get any closer, they'll end up eating grass by their burrow. Aww, what a coincidence. Lin's novel is about a scheming guy who pursues a silly senior, but one day, the scheming guy stops chasing the silly senior and realizes his own feelings. The scheming guy needs to disappear for a week, and the senior needs to realize his feelings for him. Ooh, that's a good plan.
