These are just 2 series I both enjoyed, but are very different! (You can find any series I post on mangago)
Hana no Miyako De by Takarai Rihito
Plot - The successor of the Tsujimura clinic, Motoharu has always held his childhood friend, Hazumi Akira, close to his heart. He confessed to Akira and then was rejected. Even so, he still entered the same university and same department as Akira. Ever since the confession, the two have been distancing each other, but Akira suggested that they make up and for the first time in a while, they walk home together. But on the way back, Akira suddenly kisses Motoharu, causing Motoharu's hope to grow. However, the next day, Akira tells him to “forget it”, causing Motoharu to blame Akira... I hate and love this story. It's so extremely beautifully written, but everytime I finish this manga my heart just breaks, which is why I haven't read it in a long time. This isn't recommended to people who don't like sad endings, but if you don't mind it I would recommend reading it, since it's so good.
Otona Keikenchi by Nekota Yonezou
Plot - Yumeji has a big problem, and no, it's not that he's gay (for now, anyway). Despite his good looks, excellent grades, and talent for sports, he's not getting any, and it has everything to do with the fact that he's impotent thanks to a traumatizing event back in middle school. Nothing seems to help, and since Viagra is apparently not a viable solution in Japan, he's practically lost all hope--until he meets underclassmen Seiji, who's violent, tactless, and says whatever is on his mind. Conveniently enough, he's also in love with Yumeji. This is one of my favourite series since the seme is so cute and the uke aswell~ The way they meet eachother is also quite funny, and the series just has enough comedy and fluff mixed together to make a great series!
Sorry for always posting so late, I had to post 4 in 1 day because I didn't post in such a long time xD My healthy is just extremely bad and school is gonna start which will probably make things worse, so if I ever do post late, sorry in advance. But I will always post everything I missed out on later whenever I can!
