BL series where the two main characters share a certain history together in the past but something causes them to be distanced from each other. A considerable amount of time passes (time skip) before they meet again â and everything has changed, yet their feelings still remain the same. In alphabetical order ^^
(p.s. Not all these stories have an actual romantic relationship between the characters in the past, but I still label it as under the second chance romance trope because I can đĨ°)
