Usagi no Mori
Really slow and interesting, the emotions and character development from childhood is cool to read, with Shunta and Tamaki being childhood friends at a very young age, sleeping over and spending time together. Shunta realizes very early that he has feelings for Tamaki, but remains a support friend (while secretly desiring more) and being a shoulder for Tamaki since he had a rough home life, witnessing his mom having sex at a young age and leaning away from sexual desires. But, Shunta confesses and almost awkward and sadly pushes himself onto Tamaki, kissing him and wanting sex. Tamaki kind accepts, but pushes Shunta away due to his sexual emotional trauma, to which Shunta deals with by sleeping with someone who resembles Tamaki. Interesting read and excited to see where this develops, it's a bit more complex and heavier.
