This is just "practice"! ~And yet I still want to go on a Christmas date with that girl~

I want to break that girl's expressionless face――. The prank started from such a thought! I want to see that girl's embarrassed face on a Christmas date! Rin, who rarely breaks her serious expression, and Yuka, who wants to break Rin's serious face. A comedy where you can understand the true feelings of girls who are interested in each other from different angles! ※ It's yuri, but they're not in such a fleeting romance. They'll be lovey-dovey a lot.
