Don't go for Rin as your first EVER. Not until you are properly prepared with mild feels from LIlly and Hanako. I got Rin first and I got destroyed inside.

Yea, Rin's really brought me down a notch... for i actually got the bad ending with her (first bad ending ever)... i... i couldn't just leave it at that...

Try Hanako's bad ending. "I hate you, Hisao!"

no... i.. can't do that... i just can't man

"I hate Lilly, but I hate you more Hisao!"

The suicidal bad or the "I am leaving" one?

the leaving one... there's... there's a suicidal one? D:...

Wait, I'm wrong, reread "Leaving" ending you got, she goes suicidal there. That's why she asks you to forget her.

If earlier on, during the choice in her studio, you demand she explains instead of leaving her alone, she yells "GET OUT" right there, as opposed to in your room later. That breaks you off permanently. It's heavily implied that in that case she really goes "depressed artist mode" later in her life and commits suicide. The creators approved of that theory, she does bite the bullet.

Yea, i found Lilly's and Hanako's story line to tug a bit more on the heart strings (sorry Hiaso)... so, prepare yourself
