Usotsuki Wa Hatsukoi No Hajimari Vol. 3

Kohaku Tokino is a plain high school girl. Her only friends are fossils and ruins. One day, under impulsive circumstances, she disguises herself as her beautiful younger sister and goes out when she runs into her sister’s boyfriend Oguni and they end up going out on a strange date!
After being confessed to by two guys, Kohaku’s mind is a complete mess, but she makes her choice: not the impossible-to-read Oguni, but sincere glasses-wearing Monma. You’d think that’d mean everything’s settled, but… “Something might be broken, but I can’t be sure unless I check.” Kohaku moves forward, but what ending will she choose? Find out in volume 3!
