I can't believe I'm getting 
to take care of you.
لا أصدّق أنّي أستطيع الاعتناء
بك هكذا مجدّداً
Schön, dass ich mich wieder
um dich kümmern darf.
¡No puedo creer que pueda cuidar de ti!
¡No puedo creer que pueda cuidar de ti!
C’est une vraie joie
de m’occuper de toi !
ma questa occasione
di occuparmi di nuovo di te...
nem acredito que posso
voltar a cuidar de você!
Поверить не могу, что забочусь о тебе.
