So... I left this manga to wait for some chapters to accumulate, and eventually came back thinking that maybe it had already concluded since volume 10 was (still is, I suppose) taking unusually long to release (thus, I was thinking it ended with 9 volumes)... Now, since my memory is very bad, so I didn't remember which chapter I stopped at, I just decided to reread from the beginning and see when I would reach something I didn't know, turns out volume 9 and what there is of volume 10 are the only ones I hadn't already read (despite the 3 years between then and now).
Now the important, but at the same time still irrelevant, part: I don't know if it's just from age, but it seems my heart is as weak as it can be, my once stone ice heart is now no more than a puddle, the Stargazing chapter already left me with watering eyes, as it for some reason gave me the feeling of "the end is near", then, couple it with the scene where Sakurako finally asks the question, and believe it or not, I couldn't dry my eyes for about half an hour (worse yet, just remembering it while typing this comment I can already feel my nasolacrimal ducts opening up), this manga, that never failed to make me smile and laugh for so many years, is ending...
Honestly, if it has already ended, at least the suffering would be shorter, because now I'll have to accompany the end...
That's it, sorry for the rambling.
