SPOILERS: Looking to know if this is allowed during the Hikikomori route

!So I'm preparing for a walkthrough of the game where I'll to get all achievements, and since the prologue is the same for both Hikikomori and Sunny route, I'm saving on two slots to have both ready once the routes split.!<

!However I was just thinking that I opened the door for Mari on the first night just for fun and didn't think until now if that might affect the Hikikomori route. I'm guessing it doesn't, since I've tried searching over here and no one mentioned anything about it, but just to be safe and have a clear answer:!<

!Does opening the door for Mari on the first night cancel the Hikikomori route?!<
