I just reread this almost whole thing very recently since I missed the story & even break down which chapters with which characters in it so I'll able to track them easier since I'm so forgetful and don't want to reread everything for every update. Lucky for you for an update as soon as you searched for them. ;)
Yeah it's so much confusing, especially the recent updates (including the latest chapters) so I made it organized. You can check it out (I made it visible to others on manga note section).
I plan to do this as well for Saezuru Tori wa Habatakanai but each chapters are too long so I haven't got any energy to re-read everything yet and so I somehow pause reading the recent updates.

Dude I read this when I was 25 or something, I'm 38 now and I just remembered it this Monday and searched "what happened to Love Pistols?" THEN AN UPDATE!!! Hahahahahahaa seems too good to be true, but I want the first couple to have kids, come on!!! I was here for them, I still am
