Bahasa jepang aku mencintai mu

何故こんな質問が。。。

Aku mencintaimu,
1. Suki desu
すきです(Brat confessed his/her love to the other brat)
2. Anata no koto ga suki desu
あなたのことがすきです(still the same as above, but higher in my opinion)
3. Aishiteiru
愛いしている(usually used emotionally, a very deep affection i think...)
For no 3, you maybe always see he or she who confessed his/her love in that way shed tears like... Okay idc.
