Are you people stupid? If she's so much in love with him, why HE has to be the one to confess? Can't she do that? You are calling him "cuck", "pussy", "coward", but in reality, she likes him as much or even more. Isn't she as much afraid as him? Why it always has to be the man? Quick reminder, those are supposed to be ADULT characters, not some 13 y/o kids. Both characters are stupid and the stupidest person in this entire mess is an author, who's pulling such a bullshit chapter.
Stop blaming characters and start blaming author for having no balls to say "no" to his editor, so he stalls the story, keeping it "maybe" harem, instead making an actual progress. This is what divides good creator from bad one - they value their work, instead agreeing to every shit their editor tells them to do.
