Lovesick Ellie Vol. 9 (Kodansha, 2019)

Plain (but libidinously motivated) Ellie and Year 1 heartthrob Omi-kun are now dating openly, and everything seems to be going well … until Ellie's dad catches them kissing. Ellie's dad disapproves of their relationship, and he and Ellie get into a huge fight … but luckily, with Omi-kun's encouragement, Ellie is able to make things right again. So right, in fact, that Omi-kun tells Ellie's entire family he wants to marry her … and now he's going to stay the night, too?! Could this be the moment Ellie has been waiting for…?
