But... say...

Why did you come to me for help?

Because Koishi-sama is so kind, of course.

I closed my heart because I didn't want to be hated.

There's no way I'm nice...

means you were thinking about other people. That's the way I see it.

"Not wanting to be hated"

By closing your eye... closing your heart... you hoped to stop hurting other people's feelings.

That's your kindness.

And because you're like that... I felt like I could open my heart to you.
