Yu and the Personas users were spying on Tigress Meditating
Naoto: How about you ask Tigress-San about being your girlfriend?
Yu: Huh?
Kanji: I saw the way you held her during that battle with Shen.
Yu: I'm not sure I can do this...
Yosuke: Go on partner, ask her!
Yu took a deep breath before he confronts Tigress
Yu: Hi.
Tigress: Narukami, what brings you here?
Yu: I wanted to ask if I could join you?
Tigress: Of course.

Yu sat down with Tigress and watched the sunset,
Yu: I can't believe that we saved China together again.
Tigress: Yes, well you, Po and Aigis were the ones who defeated Shen.
Yu: Well Aigis and I are Wild Card Users. so I guess you could say we're partners. By the way I have a question Tigress-san, Would you like... to be my girlfriend?
Tigress was shocked about that question, she never had a boyfriend before.
Yu looked down thinking that she was going to say no.
Tigress: Yes.
Yu: what?
Tigress: I would love to be your girlfriend.
Yu was surprised Tigress said yes, they smiled as they looked at each other and held hands. they were about to kiss until she saw the others spying on him,
Tigress: Do you mind?
"We're sorry!" Yosuke Yelled as he and the other Persona users who were eavesdropping ran off leaving Yu and Tigress alone.
Both Yu and Tigress looked back at each other and held hands. And As they leaned into each other.... They kissed.
