Okudaira-kun, the current champion of 3 of the 7 major Shogi titles, is in love but unaware of it, hence made the word "admiration" much more complicated.
Okudaira suddenly showed up in front of Arinaga, a former professional Shogi player, and said, "It's been six years, but your existence doesn't disappear in me." He then visits Arinaga everyday, and say and does everything people called "love"...
Although Okudaira is unfriendly, his emotional attachment for Arinaga also made this older man's heart full of palpitations.
