Okay think I get the storyboard from now on all 3 girls tries to get clapped but our MC bro rejects them cause he is a Gentlemannn then he quickly solves their arcs in 2 to 3 chpts each not the main girl tho after the 2 Side girls final arc begins. Big finaleee arc: MC visits main girls big old japanese mansion thingy and tries to make up with her but says something wimpy as usual and makes the girl ignore him again then MC gets depressed and starts to think how can he make this manga end then some sinister soul steps out from the shadows, its Mcs bro TAKKUN(was that his name?idk) He tells MC how he hates his guts and what sinister stuff he did to main girl 😈 but whatever he says its useless Our MC is Gentlemannn he forgives him and makes a little bro talk and of course takkunnnn softens and wants to be friends again cause its MCs bros role to that in romance genre
Lastly a final talk with the main girl and happy end.. With all this the manga should be over at chpt 70 ish if author wanna add more filler(pls no more) 80 most I think
