I have to recommend this one! This is my first BL but also my beloved! It has a tragedy ending, if you don’t mind, read this The decade of deep love. The name of the manhua is The 10 Years I Loved You the Most.
It's about a couple who have been together since the high school. They love each other deeply, but with the times, everything has changed. I don't know how to describe it exactly, I hope its synopsis will let you know more Synopsis They had been together since high school. Together, they faced the cold faces of their parents and the satirical or disdainful eyes of others, started a business and experienced all kinds of ups and downs. When their company was on the right track, Zhishu He was asked to give up his career to stay at home, while Wenxu Jiang gradually changed and began to indulge in merry-making. However, Zhishu chose to forgive him. Zhishu got an incurable disease, while Wenxu Jiang was still indifferent. Zhishu still chose to forgive him. Love had become a kind of habit, which was equal to an incurable disease. In a peaceful sunny day, Zhishu quietly left Wenxu Jiang and the house in which they had lived for a long time without an advance notice. Soon he was gone. A man with pure spirit and deep love for Wenxu Jiang disappeared from this world forever... Sometimes love cannot stand the test of time. Someone will not know how to cherish the love until he loses it...
Wait till you discover doting BL. I don't have time for tragedies and scum gongs anymore xD;; To each their own tho.
My heart is a delicate fragile glass can't handle too much tragic stuff before the waterfall starts falling. Might check out the manhua because I've seen the title before. Edit: 2 Chapters in and I'm already shedding tears.
