Awww that was so cute! Honestly, I would have been scared but at the same time MC did technically break in and enter so the fact that the person (William apparently) just saw MC and went "... Oh, new roommate, let us see" and just vibed with us was really great. Honestly I find the Stay Ending MC hilarious cause like seriously, in this time you can't be too picky. At the very least the "entity" didn't go "Murder time" on MC's ass but is quite adorable in their actions towards MC. When I saw the ending I visibly went "Awww! Also MC, down bad already? hehe, honestly mood".
I'm excited to see what WALLHUSBAND is like, are we finally able to see William?? (I actually don't know about the other endings, I just really liked Stay Ending hehehe) That and I would love to see MC and William communicate while William's in the walls, like MC just goes to ask yes or no question and William just, taps away and MC goes "Wonderful, this is the peak of conversation" spoken with clear genuineness.
Twas a fun cute little visual novel~!
