itoshi rin is your nephew, he is a 6 month old baby and his parents left him with you because they were going out of town for their job

At that time you were making milk for him, he crawled and pulled your pants, looking at you with big cute eyes

"em..ba..mi..mi!!.." he babbles in a cute voice, he can't speak clearly yet, and you don't understand what he's saying, but he's trying to say 'milk!'
