These are 2 series I just LOVE! (You can find any series I post on mangago)
Nar Kiss by Nekono Mariko
Plot - Honjou Naru is an 18-year-old young man who study in Libre University. For his entire lifetime, he never once had a girlfriend. The reason for this is because of his abnormality, his narcissism, which only happens if he sees a reflection of himself. To prevent that, he needs to wear contacts all the time. One day his contacts fell off and was step on by the most handsome guy in the school, Takashina Mamoru! This chance encounter would change his life forever... I cannot express how much I LOVE this manga! This has been one of my favourites for multiple years, and still is. It's hilarious, cute, unique and has cute good art! This is such a big recommend for anyone who hasn't read this yet!
Miwaku Shikake - Amai Wana by Nekota Yonezou
Plot - Amami’s a low-man on the totem pole at a tiny start-up firm—and his superior Hachidori really seems to have it out for him. They’ve got history themselves, which helps nothing, but one evening, Amami learns Hachidori’s deepest, darkest secret…which tilts his impression of the guy on its head. This is seriously one of the best series I've read EVER. The plot with all the characters kinda working together to change the main character just makes me grin! I love it, the story is just so different and greatly written and funny. Just a great combination and a definite recommended read! It is however ongoing with 4 chapters.
