Yozora no Sumikko de
Classmates and club members are reunited when one is a teacher and the other is a single parent and they remember how close they were when they were young and how confused feelings between them never died.
Haikyuu!! - Usotsuki Canon (Doujinshi)
Kimi wa Natsu no Naka
A lovely slice of life story of two high school boys who become friends because they're both fans of movies. The more popular boy confesses when asked who he likes and the other boy has to decide what to do. The way this manga flows is quite beautiful, I really liked this.
Hidamari ga Kikoeru
Taichi becomes close with a hearing impaired boy and starts taking notes for him in college in exchange for lunches. The hearing impaired kid is drawn out of his shell for Taichi's sunny, warm-hearted personality and that turns into love. Taichi is slow to truly realize both of their feelings. Really hope this is updated soon, it left off at a super crucial part of their relationship.
Roommates (Young Seok)
Two guys are roommates, they both like each other but are too afraid to tell each other. Lots of cute, funny interactions. They have a mutual friend who is in love with a former classmate who kinda forces himself back into his life after 5 years of no contact. I read this on Spotton until chapter 19 and then ran out of "golden keys", which you have to pay real money for. $1 per episode is so pricey and there's so many chapters. Sad :(
Unripened Expression
A mix of serious drama and cute comedy. High school boy, Jae Won, realizes that he has a crush on another boy in his class. With no one else to turn to he seeks advice anonymously online, but it turns out the gay boy, Junseo, he was talking online to goes to his school and they become friends, though the Junseo is a hard nut to crack because he's scarred by his past. I'm totally shipping Junseo and Jae Won.
Saiaku no Jinsei
Two different stories. First there's a few cute chapters of boys going out. One boy is obsessed with the other boy's nape, which makes him insecure about why he's liked at all. The second story is about classmates who reencounter each other as adults and start living together. One has it easy but is bored/indifferent with life, the other has a hard life, and hard personality but is a good guy who's misunderstood. Would love to see more about how their relationship develops.
Ganbare! Nakamura-kun!!
Super cute! Shy gay boy is in one-sided love with a classmate. This manga is basically all about is awkward attempts to talk to and be friends with the boy he loves. Cute and innocent.
Toritan
Interesting! VERY light on the romance right now but it's pretty obvious where this is heading....
