Here's a breakdown of the phrase:
* 愛 (ai): means "love"
* し (shi): is a grammatical particle that connects the verb "suru" (to do) to the noun "ai"
* て (te): is a grammatical particle that connects the verb "suru" to the phrase "ru ze"
* る (ru): is the verb "to do"
* ぜ (ze): is a casual and informal particle that adds emphasis and a bit of a "tough" feeling to the phrase, similar to saying "you know" in English.
"Aishiteruze" is a very strong and passionate expression of love, often used between close friends, family, and romantic partners. It's considered more informal and casual compared to the more formal "Aishiteru" (愛してる).
Important Note: While "Aishiteruze" can be translated as "I love you", it's important to consider the context and the relationship between the speakers. It's best to use this phrase with someone you are very close to and trust.
