Two characters have had some sort of Ship Tease, but there's no sign of it progressing to a Relationship Upgrade. Likely, one character will have feelings for the other but are resigned to All Love Is Unrequited — until the other character somehow hears (from another person directly or indirectly or from a Love Confession) they have feelings for them.
They're shocked. All of a sudden, they begin to look at the other character differently, resulting in them beginning to have feelings, too! We all want to be loved after all, and someone loving you is a very attractive trait.
This trope comes in two flavors:
- Alice already had feelings for Bob, but it took hearing Bob's feelings for her to realize them.
- Alice begins to develop feelings after she hears that Bob likes her.
This often is a cue for a long-overdue Relationship Upgrade in a She Is Not My Girlfriend or Unresolved Sexual Tension situation. A common variation is to have one fall for the other after hearing that they have feelings for them despite there not actually being feelings involved; often this set-up is Played for Laughs.
A subtrope of Love Epiphany. If Alice realizes her feelings for Bob after he confesses to Cheryl instead, that's Green-Eyed Epiphany. The inverse of this is Entitled to Have You, in which Bob loves Alice and expects Alice to love him back. If the timing isn't right and Alice realizes her feelings after Bob has moved on, it's Unrequited Love Switcheroo.
- This is what happens in Air Gear between Ikki and Ringo. The two had known each other since they were children, and though they cared about each other, Ikki only really thought of Ringo as a really good friend while she was so blatantly in love with him it was almost painful. It didn't help that Ikki was Oblivious to Love and had two other Love Interests that were more attractive than Ringo was. However, when she finally managed to confess to him, he was completely shocked, and after thinking about it for a while, he realizes that he feels the same way, and a Relationship Upgrade happens soon afterwards.
- The anime finale of Cardcaptor Sakura revolves around Syaoran finally confessing his love for Sakura, who ultimately requites the feeling and spends most of the closing movie trying to do the same.

- Makoto and Chiaki from The Girl Who Leapt Through Time are of the Unresolved Sexual Tension variety. Makoto's denial over the fact that Chiaki asked her out sets off the rest of the story as well as culminates in her ultimately accepting her feelings for him.
- A variation happens to Alibaba in Magi: The Labyrinth of Magic, where Olba tells him that Morgiana is in love with him. This leads Alibaba to go through all the normal steps and eventually confess his own love to her...until he finds out it was a misunderstanding, as romantic love is still a foreign concept to her due to spending almost her entire life as a slave. This does, however, lead Morgiana to go through her own Love Epiphany, and they eventually get engaged.
- At the end of the first season of Mobile Suit Gundam 00, when the UN Forces attack Celestial Being, Lichty uses his body to shield Christina from a blast fired at the Ptolemy by a GN-X. Due to the injuries he sustained, Lichty's cybernetic body is badly damaged and torn apart, with the boy on the verge of death. It is through this action that Christina (who previously maintained a professional relationship with Lichty despite knowing of his interest in her) realizes how great a guy Lichty really is and returns his feelings of love. Sadly, both die soon afterward.
- In the canon movie The Last: Naruto the Movie, Naruto realizes the true nature of Hinata's feelings for him, and his own for her, after witnessing her feelings for him firsthand when they were trapped in a genjutsu that makes them relive their memories. Considering Kakashi stated in Chapter 314 that Naruto is a kinesthetic learner (I.E., a direct learner, someone who learns with his body or by doing, just like his father Minato), this actually makes sense—Naruto needed to physically walk through his and Hinata's merged memories to finally understand both her feelings and his own.
- In Shikamaru Hiden: A Cloud Drifting in Silent Darkness, Shikamaru realizes that he loves and wants to protect Temari, which helps him resist Gengo's charm and find the strength to fight against him.

As she sleeps and wonders whether she'd been suppressing herself due to personal issues (she's a farmer's daughter and has a lot of "baggage"), she suddenly freaks out at the realization.
- This is a key part of the movie sequel to Tamako Market, Tamako Love Story. Heroine Tamako and her Childhood Friend Mochizou are your typical pair of Oblivious to Love meets Cannot Spit It Out. And since he's always been there, she never really noticed what he really means. When Mochizou finally works up the courage to tell her, she loses it for a while and takes a long time to reevaluate their relationship, culminating in a last-minute decision at the climax when he's about to leave.

- In the Mental Time Travel arc of The World God Only Knows, it was revealed that Tenri fell in love with Keima because another girl lied to her about Keima having feelings for her. Played With in that despite Tenri later finding out that was a lie, she remains in love with Keima for the following ten years, even though she knows he doesn't feel the same way and he made it clear to her that they wouldn't end up together, because...
- Keima himself, in a somewhat important shift from his 2-D centric ideology, ends up having one as early as FLAG 189, where he ends up shedding a Single Tear for breaking Chihiro's heart. Though such fact is still up to debate as his final words from that FLAG has been subject to various interpretations.

- In Calamity Jane Meets Doctor Isles, Jane and Maura experience subtle awareness of their attraction to each other at first, simply acknowledging the other as a good friend, but Maura only explicitly tells Jane that she loves her when Jane is preparing to leave Hollow Creek after Hoyts death, which gives Jane the kick to realise the depth of her own feelings for Maura.

- Doing It Right This Time: Comically and ironically, it is Asuka who reveals Kaji that Misato carries a torch for him still:
Asuka: You think this is some harebrained roleplay thing? Fucks sake, Kaji, I walked into your cabin on the boat carrying Unit-02 to Japan wearing nothing but a smile and you still turned me down. You're not over Misato yet, I get it. She's not over you yet either if that makes you feel better.
- Entropy and its sequel Chaoskampf has Sonic do this twice for two different reasons. One is by Milo Prower (Tails older brother) who gets Sonic to admit his love for Amy several times through repetition to get Sonic to get himself to get the idea he's in love with her. But the topic is not entirely revisited until Chaoskampf where Amy is purifying him of his corruption that he'd been trying to ignore and suppress his feelings but then at that moment, he discovers he can't deny it anymore, not to mention the only good times he's really had by this point (as the fics go into detail about how much crap he's gone through) are with her.
- Evangelion 303: In Chapter 5 Jessika often teases Asuka about her liking Shinji. At the beginning, Asuka denies it vehemently and refuses to admit it to herself, but due to her friend's prolonged teasing, she starts to second-guess herself and realizes she really likes Shinji.

- Luna realises that shes been attracted to Harry since she met him as Ginny helps teach her how to masturbate after they explain the situation to her.
- Initially just volunteering herself as part of the ritual because she can't imagine life without Harry, Hermione becomes aware that shes subconsciously thought of Harry as attractive for years before they finally admit that they love each other in Chapter 14.
- Susan Bones has a few of these; initially, after Harry explains the situation to her, she admits that she's been attracted to Harry for a while and Harry apologises for not realising this by explaining that he's hopeless with girls. Chapter 27 reveals that Susan realised her own feelings for Harry when he was correcting her posture during a DA lesson the previous year, and Harry responds to her declaration of love with his own when he actually takes her virginity.

Eventually, she and Teddy break up and Peralta and Santiago become an Official Couple.
- Doctor Who has had a few of these moments:
- Due to The "I Love You" Stigma being in place (the Doctor never actually says it to anyone), the Doctor tends to use euphemisms instead such as "I had a duty of care" in "Hell Bent", which has been interpreted as being this moment for Clara Oswald, although there are plenty of signs in preceding episodes that she shared the Doctor's feelings.

- The Doctor has this when listening to River Song talking about how much she loves him in "The Husbands of River Song" (the twist being that, thanks to regeneration, she doesn't realize she's saying these things in front of the Doctor.)

While Jake does seem to be bi, it soon became very obvious that he never had any true feelings for Dirk, and only forced himself to try it out because he was sure Dirk would push for them to date either way.
- In Penny and Aggie, Aggie becomes attracted to Penny when Penny reveals her own interest in her during a parlor game.
