As you can see at Merriam-Webster, a good synonym for "especially" is "particularly", whereas "specially" means "in a special manner". "Particularly" is the sense you want here, so "especially " will work here.
You could have a Valentine's Day gift specially made, to your own specifications, because you especially want to give your loved one something special.
There has been some usage bleed-over through the years, so the difference isn't as clear-cut as it used to be. However, the trend has been to shorten the word used, substituting "specially" in to mean "particularly". The reverse is not the case.
