Tragedy Alert! This is probably the most beautiful retelling of Romeo and Juliet I've come across, and the setting in late 90s Shanghai is so unique and memorable.
Period piece, gang conflict, forbidden Love -- 10/10
This comedic manga involves the relationship ups and downs between an obsessive Kohai and a homophobic and deeply tsundere Senpai. It may not be the most healthy of relationships at times but honestly it is so unapologetically early 2000s yaoi, and both MLs had me in stitches.
This one had the nostalgia factor going for it, because I've been keeping up with this one for, yes, over a decade (and no I was definitely not of age when I first came across it). Absolute 10/10
