Sweet shounen-ai PSP game, Cherry Blossom.
According to description, Cherry blossom~チェリーブロッサム is shounen-ai, similar to Hanakisou 花帰葬 which is another shounen-ai PC game ported to PSP. The PSP platform so far does not seem to release 18+ R-rated titles.
I don’t know much about this title but I’ve read pretty good reviews of the PC game too… about how cute/sweet it was. Shounen-ai title to begin with. Adventure + Princess/Prince Maker (?) type of game. Boys school theme.
Voice casts include: Mizushima Takahiro, Takagi Motoki, Sugiyama Akio , Midorikawa Hikaru, etc.
No luck for Nintendo DS players, cos there are no BL games for it yet.
