Hana no Mizo Shiru
Ah one of my favorites. Beautiful and sweet. Feels like a shounen-ai but with sex. If you're a romantic reader, this one is a must.
Only the Ring Finger Knows
Not much that needs to be said here. This is one of the top shounen-ai's pretty much universally. Also one of the first I read. Still love it.

Multiple stories. 1. Childhood friends meet again as adults when one takes over the others company. One has had an unrequited love since they were children. 2. Two strangers unlucky in love, meet at a bar and decide to comfort each other. SeKe. 3. After graduation, one friend asks the other if he can see him masturbate and record it. This was such an enjoyable read! It was so good to see multiple reversible couples. I also like how upfront everyone was. Cute, funny and sweet.
Renai Junkie
Take note that the final 2 stories are incest so if you don't like you might want to skip them. The main story was awesome, the first incest was hot, but the second incest really felt out of place. I've read Aitsu To Ore and thought it was okay. But as an add-on to this manga it really doesn't work. Also, I've never liked the 'I'll fuck you to get you over rape' thing. Usually when that happens in manga it doesn't actually say it outright and it's usually the uke having a change in feeling (which I can deal with), this time the seme fucked the uke with the intention of getting him over the rape. Big turn-off. Other than that this manga is very happy making.

I finished reading this manga through the Facebook translations and have to say, the story stayed interesting throughout. The ending gave me what I needed although I'm a little sad for Ren's dad. I do wish Sensei provided another chapter or two just to settle the story more firmly but overall it's a read I thoroughly enjoyed.
