「Komorebi」by alan [a song that fits IchiRuki]

The original lyrics are in Japanese. This is the translation. Komorebi means "sun filtering through trees"

You walked slower than usual
And drew in a breath whenever you stood still
I did the same; I closed my eyes and drew in a deep breath
I felt the flow of the present time
(The last line resembles how Rukia's life changed due to Ichigo, how she opened her heart to other things. It's also akin to her line in Fade to Black, where she says that before meeting Ichigo she felt like living in a straight line)

Why can’t I be more, more kind to everything?
I was embraced by you who was like a ray of sunlight filtering through the trees
(The first line referring to Rukia's tough attitude. It's all about how one changed the other. Skip the embracing thing)

Everyone cries in the same way, everyone struggles in the same way
It’ll be okay if you embrace yourself completely, you said so with a smile
(Referring to the way Ichigo & Rukia give strength, confidence and inspiration to the other)

What I found by your side, what I found by myself
These various thoughts make up who I am
(It's like if Ichigo said this to Rukia. We all know she's been the one who gives him confidence in many times. She's taught him so many things)

I can become more, more kind to everything now
You are no longer by my side, but…
(Shows how Ichigo opened himself to more things and became kinder because of Rukia's intervention in his life. Then she's not with him anymore, but...)

We’ll laugh in the same way someday, we’ll love in the same way someday
Because I have gotten much stronger. I’m living here now, too
(...he must continue with his life, in his own town, with the strength he's gained. Anyway, the verse has a sad note, as Ichigo accepted his fate even though he misses her)

There is always a light shining here by my side
The wind softly strokes my cheek and brings kindness

Everyone cries in the same way, everyone struggles in the same way
It’ll be okay if you embrace yourself completely, you said so with a smile

We’ll love in the same way someday
Because I have gotten much stronger. I’m living here now, too

I walk slower than usual, under the sunlight filtering through the trees
(This phrase has the longing and nostalgic note that always covers Ichigo & Rukia's farewells. Also notice that the first verse is about two people, this last one is about just one person)
