Managed to get a few scenes with the shota but only to run out of days because I didn't unlock his 3rd event until somewhere around day 37 or later despite starting the first two events really early. :(
Hoping someone make a guide soon.
I was hoping to play 俺のセフレはカレシ持ち学生会長 as the last game for the year but it still not on here or the usual sites :(. Also, still waiting a review for it before deciding to buy it myself.
It seems this is scheduled to be released on the 26th of this month.
Edit:
Another NTR game is scheduled to be released on the 26th.

At the moment, I'm particularly waiting for [PHASE#END] 寝取られ魔法少女〜あなたを失いたくなくて…〜 especially because it was delayed from December 2015 and it has same writer with ケンカ最強妻がまさかの敗北!メス犬調教!!.
