I love you in Japanese

Explain this if you understand Japanese

ビープ is bepu which is beep . I can't understand the Chinese character in the middle , maybe it means to repeat a word and the last world レタス which is retasu= lettuce there is nothing there that means your eyes are stars. But that Chinese character I mentioned earlier could mean an eye or to see as well . But I ain't sure about that . Sorry haven't studied Japanese in like 3 months.
