Overall: bland stories that meander without anything actually interesting happening, characters getting together because plot, lots of clichés of the genre, abrupt endings, art that is occasionally janky and all the ukes are basically the same character model.
Story 1, "Tounan Kadobeya Kare no Koi" (Love from the Southeastern Room) - 4/10 - nothing new, another case of closed-off uke (Tasaki) meeting a younger, friendlier seme (Haruki) and discovering that he's gay. Their romance...just happens, and it's based off of Haruki being literally the only person Tasaki has dated, that can relax around him.
Story 2, "20-punkan no Himitsu" (20-Minute Secret) - 3/10 - another perverted tutor story. Didn't like how the tutor molested his student while he was asleep and then lied about it, bleh.
Story 3, "Mannequin wa Warawanai" (The Mannequin Does Not Smile) - 3/10 - because they had a short talk once, normal high school student (Yabuki) pines after another student (Takanashi) who wants to become an idol. Clunky dialog, zero emotion. I get the impression that the mangaka tried to do something "deep" with this one, but it falls flat because the characters have zero depth and there's frankly no reason for Yabuki to fall so intensely for Takanashi.
Story 4, "Yopparai Mislead" (The Drunk Mislead) - 4/10 - Towa confesses his feelings to Maki while drunk, and Maki takes it as a joke. Surprise (to no one)—Mika actually likes him too! This story's main problem was how short it was, and Maki and Towa could be replaced with cardboard cutouts with no issue.
