Here is a sneak preview taken from the end of episode 2.
Kamisaka (Teppei) has moved into Akiyama's (Arisa) house starting from episode 3.
He can't stay at Harada's (Keita) house anymore because of his younger sister.
Kamisaka doesn't have money to rent a house or anything; hence he stayed in the internet cafe and looking at that, Akiyama brought him back to her house.
Kamisaka does a lot of house chores for her and from there it shows how their love will slowly develop for each other and also the gap between them.
One more thing is, in episode 3, looks like Harada is interested in someone. haha! While that girl was asking Kamisaka "Is he your friend?" Harada quickly and interestingly introduced himself by saying "Harada Hiroyuki desu!" haha! His shining eyes. So cute. Can't wait for the next episode. Here are 2 screen captures of it.
But then according to the drama chart, Sawai sensei (Nao) likes Kamisaka though and based on the chart, it doesn't mention Harada has any interest in anyone nor Sawai has interest or will be having any relationship with Harada but to have interest in Kamisaka. So, let's just wait and see how will the story evolve.
That's all for the update. Let's wait for episode 3 this coming Friday!
