It could be various phrases
But I want to listen one from you
'I love you'

A happy look on your face
Accompany it with a sweet smile
'I love you'

If you are upset with me
You'll brilliantly smile when I say it
'I love you'

A tiresome day endured
Will end happily if we tell each other
'I love you'

Life will always be cute
When we will be together arguing
'I love you'
