This just keeps getting better and better. At first I thought it would be fun, funny smut, but now there are LAYERSSSSSS that go deep. (Also, look at Hakdo trying to pretend like he’s not catchin). Ugh, I can tell this is gonna be my next BJ Alex... or at least, my next For Your Love. Every time I say no more Lezhin, I get sucked back in!

Does anyone know how many chapters left before it is complete?

Yes it's only 1 chapter left. If you checked the RAWS here chapter 7 is the final one.

Wahhh what did I get myself into? Will this manga never end? It’s been YEARS of waiting for “Onodera to fall in love” and now this too? Why do these sensei’s fear conclusion?
