Every Time...

I'm not the only one who has Hanako as a waifu but am I the only one who has never jacked of to her? Its like masturbating in front of a puppy.... Just feels wrong.

how it feels to play another character after doing hanako first

Wanna know how you get over it?

You don't.

It's what's known as a "pathetic fallacy" (pathetic as in feelings, not pathetic as in weak), and it's not weird or uncommon. It's what causes stuffed toys to appeal to children.
Basically, you have a personality assigned to that character, just the same as you do for any other human. It's only different because you haven't been given your image of their personality so much as created it.
Really, there's nothing wrong. If anything, this is cool - have fun with it!

Feels like cheating on our sweet Hanako to go on the other girls' routes?

I would be more surprised if you werent

Dude Emi was mah Waifu all summer... And I don't even weeaboo.

I feel so bad doing other storylines and ignoring her :'(

While I would advise lilly because in that route you help her as a person in much more ways than you do in hanako's own route itself. I won't spoil how.

I would also not advise lilly because there is literally a moment that you can pinpoint hanako's heart breaking when she learns of you and lilly.

If you want to begin branching off, pick the girl that is still close to her. In your case since you like Hanako, pick Lilly so you still see Hanako. And just move from there. I don't think Hanako would mind too much.

I played through all of them, the one that felt most natural was Emi, but the one I felt most emotionally connected to was Rin, I understand her method of thinking and I got frustrated by Hisao's responses since he just doesn't get it. Even though I was most emotionally invested in Rin's story I still felt like I was betraying Emi the whole time. Yes, the other story lines were moving and I felt some attachment to each of them, except maybe Shizune, not so in depth with her, but the whole time I just pictured her running alone in the mornings, crying out at night...alone...and they aren't even real!!! Playing Katawa Shoujo showed me that my relationships were entirely based off of physical attraction with limited emotional investment, always keeping them at arms length and feeling like sex was enough of a connection. As lame as it sounds it forced a reality check on my part and I miss a character that doesn't exist anywhere but in this game...

Looks like you found yourself your waifu

I have too many emotional bonds with fictional characters that can never know me, for obvious reasons.

dude, it happens to me allot, not the hanako thing, the fictional character thing. thats what i was afraid would happen. unfortunately for me i usually fall in love with someone in a dream and wake and rage
