Toriaezu Kiss Shite Kudasai
Taira's one-sided crush on Renji reaches new heights with the help of an AV. Inseparable best friends face an uncertain future when one believes the other likes a girl. Thanks to the comments section, I've been introduced to "Heather" by Conan Gray and agree it fits the last song to a T.
Ahiru no Oujisama (Kazao)
Two in one: - Our MC rescues a coworker locked in a bathroom stall and discovers it's a former elementary school classmate who's had one hell of a glow-up - Our second MC struggles with growing feelings for the effeminate Gen, a childhood friend he's kept close since finding him in his sister's skirt

Tie Me, Unravel Me, Kiss Me
A tailor determined to stay in his deteriorating neighborhood finds it hard when gangsters show up, determined to ruin it. But a childhood friend reappears and might be able to help. I prefer this author's story "Get the key to my heart" over this, but this was cute.
Tada Omoukoto wa
When Hiroya, the one-sided love of Yuuki's life, finally sleeps with him after ten years of pining (and a lot of alcohol), he calls it a mistake and vows to make things right. But while they're closer in the aftermath than ever before, Yuuki is miserable knowing he's not what Hiroya wants. OR IS HE? Also features the delightful "I thought we've been going out all this time" trope. Also also features a kickass married couple who counsels them.
Bond(z)
These are good, solid one-shots. 1 - Two friends have a drunken hookup that becomes serious 2 - Childhood friends harbor feelings for each other going back to kindergarten, but are held back by societal expectations 3 - A flower wishes to meet the man who cares for him 4 - A future heir who has been sheltered his whole life is told to live for one month with a low-level employee at his grandfather's company, who shows him the world. note to self: this is the one you look for all the time with the two friends who hook up during a heat wave
Johyou to Chuujitsu na Geboku
I wanted to see how I felt about josei. I liked it! The two I remember: a woman gets with her childhood friend; another meets a guy when she's stranded on the side of the road and accidentally burns down his late parents' house.
