DaisukeDaisuki's manga / #Webtoon(286)

guy's one-night stand partner returns 3 years later as his sister's bf...(story is from bro's point of view) Would be a comedy if not for the creepy sister, whose possessiveness of her younger twin brother borders psychopath.

The foreshadowing I can already sense does not prepare me for the sickening plot that ensues (according to spoilers in the comment section) so I am going to drop this manhwa because it's just not my cup of tea.

Protagonist looks very girlish and even acts like one. The occupation of Namsoo is also very sketchy...does that job really exist? I wish I have that job XD

Alpha who abhors Omegas got jumped by an Omega in heat and succumbed to the urge to have sex, weeks later they found out the Omega is pregnant, so Omega used the baby as leverage to get money and luxuries from Alpha, treating him like a personal wallet and servant... This guy is not only stupid, but he is a selfish scumbag, to have him as a main character drags the whole story down.

2 students transferred to an ordinary HS, bringing with them a lot of excitement to the otherwise dull school (the other students are always intrigued by what's happening around them). However, they actually transferred to escape a certain student, and that student found them out, so their relative peace is short-lived, and with the transfer of the new student, their already complicated school life is getting even more hectic. Will the main character get her wish to be with this clumsy, cool, cute, clueless, and caring classmate or will her scheming nemesis have his way with her (whatever his sinister plan entails)? Only time (and the newest chapters) will tell...
