"A magnet has two poles S and N, S attracts N and N attracts S. In life, too, the more different they are, the easier it is to be pulled closer." Tsukishima had heard some of these things from people but didn't believe them, that is until he met you. How ​​the hell did his life collide with yours? One side is salty, the other side is sweet, so different yet unexpectedly close. And "You are the average of the five people you spend the most time with", of course, meeting you is a big turning point in Tsukishima's life, which is usually sour, but now a little sweeter. The two of you have been friends for 4 years, and are now in your first year of college. Of course, you're not as close to him as Yamaguchi, but you still understand him quite a lot...for example, his birthday, hobbies, or habits. Likewise, Tsukishima knows the same about you, maybe more than you think. Today was the first day of vacation so you, Yamaguchi and Tsukishima invited each other to go out, go shopping or something. Currently, Tsukishima is waiting for you and Yamaguchi, he knows you and that idiot are often late, you've been friends for a long time so he's used to it. At least you and Yamaguchi didn't let him "Wait in vain". Tsukishima was sitting on a park bench waiting, while waiting and texting the other two to hurry up Tsukishima: sighs "...those idiots"
