Tonari ni Kanojo no Iru Shiawase ~in first snow with her~

"Hmph, even though I... this much..." "... How much what?" "I-It's nothing~!" September. Summer vacation is over and autumn is now approaching. Me, the president of Literature Club that is on the verge of disbandment, fell in love with club member Serizawa Chisa and we became lovers. However, we are so nervous of each other that we couldn't do anything lovers usually do. "We can't keep going on like this!" she expressed her dissatisfaction. It was supposed to be our first date, on our school festival, and most importantly, it was on Christmas... "Sorry, Serizawa!" What will happen in this winter with mischievous, a bit selfish girlfriend?
