Graduate student Souichi Tatsumi is demanding, violent, tyrannical...and a homophobe. So, it's unfortunate that his best assets are a beacon to the homosexual eye: his ass and crotch. Unfortunate, indeed—for both him and his underclassman -slash- lab assistant, Tetsuhiro Morinaga, who is hopelessly in love with those assets despite the threat to his own personal safety.

Morinaga longs to tell Tatsumi how he feels, not to mention other longings... but, given Tatsumi's personality, Morinaga has a better chance of winning the lottery.

Here we have a story about the goofy Morinaga who has been hopelessly in love, for 5 years, with his egotistical-violent-grumpy- homophobe sempai, Souichi…ahem!, yes, that is The Tyrant.

You guys maybe have seen lots of these stories, so, the conspicuous word here would be homophobe, this is not an euphemism, Souichi hates homosexuals deeply since his little brother was “taken” by one (figures, we have also a brother complex here). But isn't it kind of strange that in spite of knowing about Morinaga’s crush on him he acts like that didn’t happen at all?

As expected, the "poor" goofy guy feels that there is nothing more read more

The Tyrant who Fell in Love in an entertaining romp sure to give you some laughs and leave you with a grin on your face. It features a pairing I've never been able to resist; an older, tsundere uke (Tatsumi) and a more reserved seme (Morinaga) who pursues the relationship. If you're a fan of the Egoist couple of Junjou Romantica, you're likely to enjoy this couple.

So we have Tatsumi Souichi, a self-proclaimed gay-hater whose two favorite people in the world...are gay. He's a classic tsundere; loud, brash, hot-headed but also a bit shy and easily flustered. I think what makes this 'walking personality disorder' read more

Koi Suru Boukun~! It's like, so different from other yaoi manga!! Gosh, I'm sooo tired of that stereotypical crap, let's get some backbone into my ukes!

Oh how shortsighted the thought is. Well then, let's go.

Plot: Rape is love.

Contradicting homophobe has a gay best friend and a gay little brother. Said best friend is in love with him but "doesn't attempt anything because it might ruin their friendsh--" wait no, Morinaga has no qualms about raping the man he's been lusting after exclusively for the past so or so years when he gets an opportunity to do so. This was never about friendship and all that read more

I have only recently started reading this series and fell head over heels for it. It reminded me of "the book" that started my gay romance frenzy. It was a "straight romance" book that had a bromance on the side that unfortunately for me never blossomed. I love the "I am only gay for you" relationship where love has no boundaries or sexual orientation.

I also don't normally go for the skinny types but this story was an exception:

the dominant male being the uke
lab research and scientists
forbidden love
gay only for you relationship
Some straight characters with a strong role in the story
And it's so darn funny! read more
