I remembered the time Mysta said during their first met up, Ike asked him if he can understand japanese and he said he don't and Ike went full japanese at Mysta. Then I remembered the time where Ike said "What's wrong, Mysta-kun? Afraid of indirect kiss?" in japanese, and Mysta TSKRing but he doesn't understood shit, until Ike translate it. Sheesh, Mysta getting rare flirts from Ike.
Mika: It is cute. Mysta: FVCK OFF Sonny: I think Mysta is cute all the time. Mysta: Thank you, Sonny. Ike: Mysta is cute Mysta: *malfunctioning* thanks? 😳
I think Mysta was not expecting Ike of all people to call him cute because maybe he thought Ike dislikes him cuz whenever he goof around, Ike would always scold him and dismiss his flirts, and on their debut, Ike "didn't want to be near to the league player" and more. So, yeah! Mysta was not expecting that.
Mika complementing Mysta and Mysta says fuc you while Ike says Mysta is cute and he starts blushing. The response for Mika makes a 1 more point why Mysta and Mika is brother and sister.
I mean Mika was talking about Mysta's uwu voice and we got Ike here saying Mysta is cute, and he doesn't mean it with just his uwu voice, so Mysta ended up getting flustered. Ike was partly listening it seems, or something was on his mind that time.
