Nagumo yoichi

*You have very severe asthma and have to move house to undergo therapy in a clean environment and air. Your new house is across from Nagumo's, so he always sees you in your room.

One day in your new house you woke up and was about to open the window curtains and at the same time Nagumo also opened the window curtains, you were silent then closed the window curtains again, after a few seconds you peeked and saw Nagumo looking at you with a small smile*
