Why did you translate it so she said "oppai" on page 4? By that logic shouldn't he have said "kawaii" instead of "cute" on page 5? Translator's baka! (Baka means keikaku)
Plot twist: She's yandere and stole his phone in order to stalk him. Now she's being pushy in order to go on more dates with him and further capture him in her web.
I honestly have no clue what she is talking about in panel 2. Did I miss something?
Edit: I didn't even realize April Fools was two days ago...time flies I guess.
@So-chan
He didn't need to spare her feelings he was just doing his cool older brother a solid by protecting his secret santa identity.
Can Aikawa-san be my santa?
