This manga is short but amazing and chapter 5 last panel is a major shookt and plot twist to me. So Ouchiro his been secretly crushing his childhood friend until he met Inamura. Inamura is the biggest plot twist here he is the easy going type of character but damn he revealed in chap 5 that he was in love with his older brother bit then again when he met Ouchiro love blossoms and he was able to move forward and in the end ,5 years later their relationship is still growing strong and now their moving in together.
