ok so I accidentally refreshed a mangago page and can’t find what I was reading

the name wasn’t in English
it’s a yaoi
in black and white
They were scientists at university, and the one black/brown haired guy has had 5 year or so old crush on the other scientist dude who has long hair which is blondish from what you can see??
The blondish haired dude is homophobic and doesn’t support his brother getting married to a guy. The other dude has already told blonde that he had a crush, but blonde ignored it. Suddenly, the other dude went to a bar and got a drink that makes somebody more… sensitive . He doesn't want to use it on the blonde haired dude at first, but the blonde-haired dude drinks it under the impression it's alcohol. At first, black/brown-haired dude thinks it wasn't real but the effects kick off at night.

I think that gives a pretty good description of it, if you know pleeeeease tell I was just getting to the good point.
