Darren Espanto tells Cassy 'I've got your back,' and to Mavy, he's 'always here' on their birthday

Mavy and Cassy Legaspi have just turned 21 and their friends are going all-out to greet the twins for their birthday!

After Kyline's very cute greeting for Mavy, singer Darren Espanto took to Instagram to greet both twins.

Posting BTS videos, car rides, and private hangs, Darren greeted "the two most genuine people I’ve ever met" and thanked them "for always being there."

Turning to Mavy first, he looked back to the dance prod they did six years ago when they were just 15 and said it felt "just yesterday and now you’re turning 21."

"Thank you for being our designated driver, always," he first joked Mavy and expressed gratitude "for being someone I can always count on."

"Always here for ya," he added.

Turning his gaze on Cassy, Darren first gave in and called her Jisoo and then said Cassy has "been with me through my highs and lows." 

"Continue to be the badass that you are! You’re one of the strongest women I’ve ever met and you never fail to impress us," Darren added.

Pointing out how Cassy is always there for her family and friends, Darren wished that she would "set aside some time for yourself as well, ok?"

"I’ve always got your back!" He promised her.

"I’m happy that the things you guys only dreamt of doing before are all coming true and this is only the beginning! I wish y’all nothing but success and happiness always. Love you both!!!" the singer ended his greeting.

Around Valentine's Day last year, netizens made a huge ruckus out of Darren and Cassy's conversation about cup noodles. The rumor resurfaced again in November when people wondered whether or not they spent Halloween together.  

In any case, here's proof that Darren is close to both Mavy and Cassy. — LA, GMA News
