Ore To Joushi No Kakushikoto
A selfish boss and his subordinate end up in a hotel because the trains have stopped running. The boss, too drunk to recognize his coworker, comes onto him and asks his subordinate to film the encounter, giving him the perfect weapon for revenge. Only the more they get to really properly know one another, little by little, their relationship begins to change. I almost skipped this and am so happy I didn't. This was a fantastic love story, well paced and believable. I agree with other commenters who said this has the best confession scene they've ever read!
Bouai Friendship
Surprisingly sweet with character development and a happy ending! Yuzuru is known as the ghost senpai because he never speaks to anyone. When he drops his pencil case, it's picked up by Kyoya, a popular and arrogant junior who coerces Yuzuru into a sex-friends relationship. What begins as coercion becomes genuine, but as Kyoya is beginning to open up to him, Yuzuru makes his own friends for the first time and is approaching his graduation. Explicit; I scrolled past those parts. This would've been just as effective without it. The twist: Kyoya used to move a lot as a child and lost the friends he made quickly. When new friends turned on him at a previous school, he resolved to put on fake airs and never let anyone close to him. He'd noticed Yuzuru, who reminded him of his past self and made him realize he'd become the type of person he despised. He hadn't intended their relationship to last, but hadn't ended things because Yuzuru kept coming to him.
