Where does the “plot” start?

There isnt really a "plot" I would say since throughout the manga you just follow punpuns life, but there is a lot of foreshadowing in the start of events to come. It's a lot of building up, but I find it all very interesting in the long run, it's really only until you're really into the story of punpuns life where you begin to question everything, sorry that I cant give you a specific point ╮(￣▽￣)╭

Thanks for the help! (⌒▽⌒)

This is slice of life, so basically it’s just a story of a segment of someone’s life. Doesn’t really have a defined starting point just like how life usually is. This type of story is generally read to escape into another person’s life (not the case for this manga lol), but if you want my opinion, the plot starts when punpun break his promis to Tanaka.
