Kawaii Shinyuu wa, Tokidoki Otoko
Mashiro met her best friend Omi in college, and though Omi is actually a boy, he's so cute that Mashiro has always seen him as a girl, and the two have even moved in together. But when Mashiro is getting hit on at a party, a handsome stranger swoops in to her rescue and reveals himself to be Omi. Now that Mashiro has seen Omi as a man, she can't get him off her mind! Cute but honestly could have taken like four chapters. Trigger warnings: dubcon, stalker, online harassment.

Meanwhile, his coworker Aki is known as a cold and unapproachable woman, but in her private life she dresses like an ambiguously gendered punk.

Cute and interesting reversal of norms and expectations. No trigger warning.

After a war between clans, the clan leader's son, Heuk, is sent the daughter of the losing clan's leader as his bride to ensure peace between them. Little does he know, the bride was replaced with her twin brother, Jayeon, who has instructions to kill Heuk. Although his clan doesn't trust Jayeon, Heuk can't help but pity the poor child when he sees how young his bride is, and his pity touches Jayeon's heart, so that he wants to stay there forever. The only problem is that their clans still intend to go back to war, so if they really want to stay together, they can't stay there. Also Heuk still doesn't know Jayeon is a boy. Trigger warnings: abuse, child bride.
