Blue Gray no Kutsuoto
I'm crying??? Set in a historical time period; childhood friends confess their love before one leaves for three years. Shoes as metaphor.
Liquor & Cigarette
Teo, the lightweight owner of a liquor store, "trains" with his childhood friend Camilo in order to take part in the city's wine tasting festival. He uses their drunken evenings to explore his confused feelings for Camilo. Though Teo loves him, he's frightened by the idea of having sex while simultaneously afraid to give him up. The art in this is gorgeous, the relationship mature, the friends supportive and friendly. Marking this dubcon since Teo is asleep when they start at many points, though it was vaguely agreed on each time in advance.
Megane To Koi To Aoi Tori
A plain boy with glasses is the target of his attractive best friend's attentions, but is concerned he's not good looking enough for him. A cold boy constantly makes passes at the boy who sits behind him, Kuraki, who doesn't know whether to believe the things he says. When it seems domestic abuse might be a problem at home, Kuraki invites him home. This was the sweeter of the two. I would've loved ten more chapters about them! Features the baby that keeps sleeping with them.
Mahoroba Days
A descendant in a revered line of deer is in love with a human who has served his family since childhood. This is a little confusing at times, and the MC is a tsundere to the nth degree, but it has sweet moments. Head's up for a guy coming onto his adopted brother.
Kimi no Tabegoro
Childhood friends dance around their feelings (well, one does) for five chapters and then have sex with a lot of food puns.
Nozomu Bekumonai
When his childhood friend cockblocks him at a group date, a man asks him to take the place of the girl he chased off - and he agrees. This leads to a wishy-washy relationship because of insecurities, but things work out in the end! I wish the author had spent more time on the "substitute for a girlfriend" portion so we could see the emotions build a little bit more before the "omg, i'm in love!" realization, but this was nice. ETA December 2021: I didn’t have any trouble with the timing of relationship revelations this time. This was really sweet. I probably read it too quickly the first time.
Kujira no Oshitate-san
Once close friends whose relationship has turned bitter run stores that face each other: a traditional kimono shop and a tailor's shop. When the kimono shop owner is set up on a marriage interview, he's shocked when the tailor, who had left him for a year to study, interrupts it with the confession that when he'd thought of their future, it had always been together.
Kiss Mo Dekinakatta
Guy nursing a broken heart seeks comfort from his childhood friend, who is in love with him. Unfortunately suffers from pacing issues that keep this from being as effective as it could'd been.
Warui Otona ni Narimashite
Natsuno is dismayed that Ui, his best friend from childhood, has lost all memory of him after an accident. In a ploy for a place to crash, he tells Ui they used to be lovers. But was Ui telling the truth about not remembering him?
Kyou Kara Omega ni Narimashita
