Suki wo Choudai
Multiple love-related one-shots... I think many have this theme of "insecurity", which is all too common in a relationship. The stories were alright, just nothing really memorable.
Genshaku Tsundere Danshi Semekare
I think it went from "okay" to "so predictable and annoying, I got pissed off". The first story was the only sort of decent one, and it seemed like each story afterwards just kept getting worse than previous one.
Sensei, Suki
Series of stories where the teachers end up having sex with their students the moment they both acknowledge their feelings for each other.
Boku No Sekai Kimi No Real

Yuru Koi
First 3 chapters have the story of a girl that moved back to her parents' village, there she met and fell in love with a young potter. Second story is about a student teacher, who had her practice in her old high school. There she met her former student teacher whom she had fallen in love with, but now he's a full-time teacher and helps her out in her practice. Third story is the final chapter for the first story in Heart no Ousama, it's very slice of life, tells how they celebrate Yui's 24th birthday. I really, REALLY love how the mangaka is able to truly show how the couples express their love for each other, snuggles, kisses, hugs, caresses, they're all able to convey their intended feelings and emotions.
