Saeki San to, Hitotsu Yane No kaI'll Have Sherbet! 2 (Famitsu Bunko) [Light Novel]

[Machine Translation] After the Golden Week holidays, Kyoushi Yumizuki, myself, and Mr. Saeki, who is one year younger than me, have been living together fortunately (with a few exceptions) without anyone knowing about it. I was busy dealing with Mr. Saeki, who was relentlessly closing the distance between us at school, and Mr. Sparrow, who kept an eye on my movements, but then for some reason Mr. Horyu began to provoke Mr. Saeki. This is the second act of the school love comedy of the always calm Yumizuki-kun and the extraordinarily beautiful, but a little bit H-money Saeki.
