Although "aishiteru" is the Romanised form of the Japanese for "I love you", it's worth noting that the word isn't actually used very often in Japan.
Its most common usage by far is amongst weeaboos (see also wapanese) where you'll almost always see it spelled with the Roman alphabet like it is here.
Aishite is a Japanese word for "love me."but in a physico way.Saying aishite to your lover is kinda wrong and your lover will think you are some kind of yandere.
