The ending did it for me, though luckily not because it was sad but rather because it was so heartwarming. :') Glad to see such a tragic story have a happy end.
Pretty sure Shikatani's backstory made me tear up at least once. If nothing else it definitely tore at my heart and was very hard to read through. For a smutty comedy manga YBC sure packs a lot of punches to my goddamn heart.
Update - Jun 12th 2022: Almost cried while reading Ch. 23, the love triangle had my emotions running high and I felt so bad for Kashima but also so conflicted because of Yacchan that I damn near passed out lol.
Ch. 39 especially made me nearly cry, it resurfaced my own school memories to the point where I felt a gutwrenching desire to go back in time. Graduation is the epitome of bittersweetness and that chapter captured the mood of it perfectly, to the point where it was painful to read.
I relate to Masaki's social anxiety a lot, and the way Takeru was so understanding and caring really pulled at my heartstrings. If someone was that nice to me irl I'd probably start crying immediately lol.
The ending of Chapter 3... </3
The ending of Ch. 5 was soooooooo adorable that I just aghhhhhhhh!!!! ;_; Happy tears...
So much pain, this whole story, but the very ending fucked me up.......... I just wanted to have a good time reading Dakaichi and they threw this at me................
