Bitter Virgin
I started this manga on a recommendation from my dear friend Eva. It was really good! I do think the characters act too silly/lighthearted for the serious topics handled at some points, and I think it resolved too quickly. However, I think Hinako's past was handled very well during the flashbacks even if I think she's lacking as a character outside of her trauma.
The romance itself was very cute and the uncertain ending was nice because they are in high school. Who knows if they'll continue dating for the rest of their lives.
Daisuke is cute as hell and I was not expecting him to be so kind!
It's 4 volumes and can be finished pretty quickly as there aren't many panels or words per page. Do recommend!
