The morning next day, it like previous day Isao start walking around Osaka looking for food. It has been his routine since he arrives at Osaka. While waiting for the food to arrive Isao decide to text with Mina.
Mina finishes breakfast and lying on her bed. Suddenly her phone is beeping.

One new message from Isao-san

["Good morning Mina-chan, Did you wake up already?"]
The blood rushed to her face when she is reading the message,
'Isao-san change the honorific.'
She quickly replies to the message, and she doesn't want to let Isao waiting too long.
["Good morning Isao-san, I’m already awake just finish my breakfast. Did you eat your breakfast?"]
["I am waiting for my breakfast right now."]
["Did you eat outside?"]
["Yes, there nothing to eat at Haruma house. So I looking to eat outside and after that, I can keep looking new restaurant here. It has been a while since I come here."]
["Woah, I am jealous of you Isao-san. You can go to travel anywhere. Did you travel to find a good restaurant?"]
["My main objectives to find a good restaurant other than that I also want to find a figurine. Nothing impossible Mina-chan you can do it if you try. How about you show me an interesting place in Korea next time to go there?"]
["You will come to Korea? When?"]
["I am not sure yet, but before the end of this year, I will come to Korea again. I want to finish my annual leave there a lot left."]

They talked a lot, especially about work and music. Isao really likes her music, and they end up talking a lot. Times was moving really fast, without them knowing, it’s already mid-afternoon.
