I'm happy for you

We arrived in front of my house I knock and one of the maids welcomed me and escort us to the living room where my parents are. I greeted them and I introduced Haru to them,. " I'm Haru Toriko nice to meet you", My parents stand up my mom came towards Haru and my dad came towards me, he put his right arm on my right shoulder what's happening? did I do something wrong? he looked at me and said " I'm happy for you", Huh? What do you mean your happy with me?. " You two are so young but it's good to start early". what start early? I look at Haru she is looking down and being all flustered what's up with this?. " What's happening?!". My mom and dad looked at me and they said " your not getting married?". How did you two get on that conclusion?!. We talked and clear things that misunderstood. So bringing a girl in the house on your parents is a sign of marriage here so that's why she's flustered and nervous, but she agreed right? right?. I look at her and she is still flustered, After that I introduced my parents to Haru, " Patrick and Hana, my parents". We talked and I said my situation in magic academy they were ok that I'm in class seven, what's important is i'm enjoying myself they say, what an understanding parents I have.
