Good. Glad to know. ^w^
Also don't worry. I'll stay tuned ;3
And yeah, somekind of an unexpected ending with Rob is what I'd have in mind, like interacts with him enough and during in one of the main routes, he unexpectelly appears to you out of blue and you get a Ending with him.
Like he abruptly interrupts your persue to the main characters, depending on how much "interacting points" you have with the characters lmao xDDD
