Hi. I got the 2nd ending on my first run. Here's how I did it:
*Spoilers* below.
-Wait, too?
-Yeah, I'm excited to explore the area!
-Everything sure looks worn out.
-The dust sprites! They got me...
-Maybe because they need too many renovations?
-(Try to cheer him up)
-(Offer him a hand)
-(Offer him gloves)
*I then chose all 3 options of conversation before asking Towa what he thinks*
-I usually spend time by myself.
-I'll take you on a date-
-Yeah
-Are you really... A Kami?
I hope this helps :)
