Oh, i see where this is coming from.
This series works as an epilogue for every rom-com out there where the MC is a dense motherfucker (tho it looks like this one was a popular one with the ladies) that needs over 200 chapters (plus all his childhood and adolescence that took place before the start of the series) to notice that his childhood female friend is in love with him and he also likes her, while their friends acting as wingmen and wingwomen and end up becoming couples before them.
Yeah, one of those series where the author thinks "im gonna play the setting of him being too dense to notice and her to coward to confess to squeeze money from the readers for 4-5 years and then wrap up a conclusion in a few chapters whenever it drops in popularity, i get bored, earned enough money or i feel its about damn time to end it, finishing it as soon as the main pair gets together".
Legit.
