Ashita wa Ieru Kana
From Hoshikuzuu Scans:
Oda Ayumi is in love with her childhood friend, Ootani Ichita, who is actually also in love with her but is too shy to take the next step. Ootani was practicing his confession when he was overheard by classmate Takatsuki. Now Takatsuki is helping Ootani… even for a good friend isn't he too dedicated?
