Many Thanks to Faithful Magewhisper for proofreading my translation!
My father's expectations I disappointed -
I was too human.
My mother's loving care I rejected and hurt her -
I wanted to be a Vulcan.
The spear in her heart is the spear in my own -
I am her.
T'Pring preferred cool logic to anything I could offer her -
me, the half-blood.
My companions I selected carefully, swore to serve them, to protect them.
Particularly the one.
The one who knows me and loves me.
Him, who sees through my logic and recognizes the heart, which is beating for him –
will always beat for him.
I love you, Captain, is written in my heart.
