Forgot the anime ost

I really want to remember which song is this, but I can only recall a part of its lyric. It goes like this:

. . . . soshite shimaundayo

Or something like that. The song is calm and relaxing.

I tried to Google using that word but no right result come up.

Please help me (it's been a year, haha)
Thanks

 

Can you remember the anime it is from

 

I would like to put request tag on title, but it looks like I can't edit the title. Sorry

 

I tried to, buy it seem that I can't remember the anime

 

Anything else that you remember? Just anything. Q.Q

 

Write what the anime plot is or give a summary.

 

Then how about a description of the characters

 

Two words of the lyrics...that's not a lot to go on...Do you remember anything else?
Like the plot of the anime? The setting of it? The characters?

 

The singer is female

 

.............................
orz
more?

 

The best I could find was Zetsuen no Tempest Ending 2, but that's by a male singer and contains the words "sagashite shimaundayo"
Probably not the right one, but the only thing I could really find :/

 

Chihayafuru 1 ending, Sochite ima?

 

How does guess who amd clue even sell or exist anymore when you can play the expert version right here

 

High chance is this
I watched zetsuen no tempest, love some part of it, and can't exactly remember the lyric. Hence "or something like that"
Thank you, but lemme check it first

 

It's improbable that it is this one but we'll see in a bit I guess.

 

Sadly, it's not, the song is calmer than this and the singer is female
Probably one of supercell/egoist singer

 

From Guilty crown? I remember hearin something like that
Try departure, guilty crown

 

Checked and, nope. the song is a bit mellow, I think.
But thanks for the suggestion

 

If EGOIST or Supercell, then its should be either Guilty Crown or Psycho-pass.

 

High chance
I used to listen guilty crown ost when travelling far away, and become supercell fan because of this

Can you please point out one song?
