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.

Preliminary (26/? eps)
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 ...

Mixed Feelings
Preliminary (4/? eps)
The author of this manga always has beautiful artwork, but the story and personalities of the characters in it did not make reading this an enjoyable experience. I read it for 4 hours starts and got to about Vol. 4. I was so fed up with how Souichi beats up emotionally and physically on Morinaga. I wanted to read it because of it's high rating (almost a 9/10), and because it was a recommendation from another manga that I really enjoyed but...

Basically, this manga did not have enough mutual love in it for me. And all I could think about was how much I hated ...

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 ...
