This contains spoilers for the whole Series, you have been warned. Speculations say "Most of the characters" could be singing Love Like You, what I think is Rose Quartz/Pink Diamond is singing this to Steven. Not in a confession way but more of a doubt way. I'll explain to you guys.
If I could begin to be
Half of what you think of me
Rose did have some thoughts on what Steven would be when he's born, it's painfully weird to think that she said she was going to be half of him, and the song says half of what you think of me. I think what that means is that during the first few seasons of Steven Universe (Before the Pink Diamond reveal). Rose Quartz wanted Steven to think of who she was as Rose and not Pink Diamond. Because of all the bad stuff she did as Pink Diamond she thinks he might think wrongly about her. And judge her for her actions as Pink Diamond. More of this is explained in Diamond Days and Future. Mainly Future.
I could do about anything
I could even learn how to love
She wants to bring Steven into this world so the other gems and her can learn how to love, as she didn't know what love is prior to meeting Greg, she even asked what love was (Greg called it torture and she asked him is this torture).
When I see the way you act
Wondering when I'm coming back
Its widely known that Steven is half of Rose and her data exists somewhere within's Steven's gem. So she as she states in her tape to Nora basically but Nora is Steven. "A human is an action. I wonder who, how you'll be, what you'll think, what you'll want. Oh, I'm so happy for everyone who's going to know you."
Which implies she wants to see they way they act. She's never coming back as she states as well "Steven, we can't both exist. I'm going to become half of you."
I always thought I might be bad
Now I'm sure that it's true
This again references her as Pink Diamond, she is worried probably if Steven finds out about her being Pink Diamond he'll think less of her, and this emotional toll gets worse as she thinks she's probably bad for all the stuff she did.
'Cause I think you're so good
And I'm nothing like you
She thinks Steven will be good, and she knows she won't be anything like Steven considering all the bad stuff she did.
Look at you go
I just adore you
Again she adores Steven because she's making new life on earth, she wants to see him go, and grow as a human being.
I wish that I knew
What makes you think I'm so special
Rose wants to know why Steven thinks of her as special despite her past as Pink Diamond, what she doesn't know that she is his mother, and a child still loves their mother regardless of something they did in the past (Some people won't but Steven actually does this, and doesn't want to hear any bad stuff that his mom did.)
If I could begin to do
Something that does right by you
This can be interpeted by many ways, maybe shes singing this to someone else? Maybe she's thinking giving up her form to have Steven is doing "right"
I would do about anything
I would even learn how to love
She thinks she can do anything to help her case, and having Steven changes her perspective on learning how to love.
When I see the way you look
Shaken by how long it took
Rose wants to see how Steven looks, and is shocked to see how long it took for him to fix her issues she left behind as Pink Diamond.
Love like you
Love me like you
This also means she can love him. And she can love like him.
I KNOW THIS IS STUPID BUT THIS IS A THOUGHT I HAD AND WITH THE SPEECH SHE GAVE TO STEVEN/NORA HOLDS MORE CLUES
