What does two hearts under one umbrella symbolize?

My boyfriend sent me a picture of two red hearts ♥️♥️ Under an umbrella ☂

"If two people share an umbrella, it is called the “Ai-Ai gasa”. ‘Ai’ means ‘love’ and ‘gasa’ is the variation of the word ‘Kasa’ in Japanese with the meaning ‘Umbrella’. And literally “Ai-Ai gasa” means “Love-Love umbrella”. The Japanese youngsters use the symbol of an umbrella with the name of the boy and girl on its both sides as a symbol of love. It’s similar to the heart symbol representing love. Two people, especially a man and a woman, sharing an umbrella in rain is considered as a symbol of romance in Japan."

That comes to my mind
