i can’t give u an exact number but i can give you my personal speculation as a novel reader; one more season after this one concludes (primarily focusing on their romantic feelings for each other and how they act as a couple) including side stories (based off the novel, they don’t have proper penetrative sex until the very end because the seme is an inexperienced virgin) about their more intimate life
i think this season will conclude when the reveal happens that they’re neighbors.
however pls take this all with a grain of salt im just a wee lad with a semi functional frontal lobe on the internet, i could absolutely be wrong. just my opinion!
imma just wait for them to fuck
