Can anyone remember this Eroge title?
-The Cover Image on VNDB has the 5~6 main characters standing (full body portrait) and facing the viewer, it's a white-sky-blueish background, and has the title name as well.

-has a glasses-wearing main character guy, and a spiky hair delinquent-ish guy
-Has a blonde (american?) heroine
-blond heroine has a CG where she is in a body of water, wet, and her skirt is floating in the water CG.

-has a blue hair heroine (with two hair styles in CG, long hair, and in a single hairbun), I think she also has "tareme" eyes
-school setting
-blue hair heroine has a boyfriend with spiky hair
-first cg of the blue hair heroine is her having rooftopsex with boyfriend (she is wearing her tied up hairbun style in this CG)
-blue hair heroine has CG where she can cheat on the boyfriend with the glasses wearing guy, in a 3P (threesome) CG scene.

-The VN has a similar artstyle to "Green Green OVERDRIVE"
