My forehead is always there 
for you to lean on!
!جبهتي هنا دائمًا من أجلك لتتّكئي عليها
Du kannst dich jederzeit
an meine Stirn werfen!
¡Siempre puedes apoyarte en mi frente!
¡Siempre puedes apoyarte en mi frente!
Dans ce cas, colle ton front
au mien quand tu veux !
Puoi poggiare la tua fronte sulla mia
tutte le volte che vuoi!
A minha testa está
sempre aqui pra te apoiar!
Ты всегда можешь
положиться на мой лоб!
