"Follow Love and It Will Flee Thee, Free Love and It Will Follow Thee" is the fifth episode of the second season of the anime Sekai-ichi Hatsukoi. The episode revolves around Ritsu Onodera and Masamune Takano.
While trying to deal with the stress at work, Onodera gets an unexpected phone call from his "fiance", An Kohinata. After stepping out to take the phone call, Takano learns from Kisa that Ritsu left the room in order to talk to his "girlfriend", much to his dismay. After barely convincing An not to come by his work, who instead says she will show up at his apartment, Takano comes up to Ritsu after the end of the phone call. After discussing Ritsu's "girlfriend" situation, it ends up causing a rift between Ritsu and Takano.
In the train, Takano gives Ritsu beer, telling him to come over to his place. Ritsu, however, turns him down and says that he can't. Suddenly, there is a sudden power outage and, taking advantage of the darkness, Takano kisses a stunned Ritsu. Takano then begins to ask Ritsu about his phone call earlier, but the lights abruptly come back on - ending the moment.
As Ritsu and Takano walk home, Takano takes Ritsu's hand, holding it as they continue to walk. This makes Ritsu slightly irritated and he tries to shake his hand off to no avail, pointing out someone may see them, which does not faze Takano. After a moment, Ritsu becomes comfortable with holding hands. As they keep walking, a girl calls for "Ricchan", Ritsu sees An waiting for him outside the apartment building.
Letting go of his hand, Ritsu runs to her surprised by her visit. Takano, also surprised, walks towards the two. An has come back from Paris and was waiting for Ritsu so she can give him presents. An asks how Takano and Ritsu know each other, with Ritsu referring Takano as his neighbor. An then introduces herself to Takano and thanks Takano for taking good care of Ritsu. Takano asks Ritsu if An was his girlfriend, to which he claims no, much to An's dismay. Takano walks into his apartment while An decides to head back as well. After a moment of looking back at An and Takano, Ritsu decides to make sure An gets into a nearby taxi. While An excitedly talks about her time in France, Ritsu silently takes note of how Takano may misunderstand the situation, wanting to properly explain to him.
After getting back inside, Ritsu reminds himself how he and Takano are not dating and he has no true need to explain things. He also recalls how he has other business assignments to tend to and he needs to look on building himself up. However, he deeply wishes to anyway and decides to visit Takano after all. Ritsu visits Takano and, as an excuse to be there, gives him mochi by claiming he made too much for himself. Takano takes the mochi, giving him a simple and polite thank you.
Before Takano can close the door, Ritsu holds the door open himself and steps inside before beginning to explain that An is just a platonic long-time friend of his. Takano, however, doesn't believe him and bluntly states she is his fiancee, leaving Ritsu stunned. Referring to how they make a great couple, Takano tells Ritsu that he is going out and leaving. Ritsu casually asks if he's going to a convenience store, but Takano tells him that he is going to see his cat - who is with Yokozawa. Frozen, Ritsu lets Takano head for the door before abruptly turning around and grabbing a hold of the back of his coat. Ritsu then tells Takano how it is was his and An's parents that arranged the "fiancee" arrangement and how they are like siblings, but that is all. Takano says how An appears to really love him, pointing out how she waited in the cold until her face turned red just to see him, calling him dense when it comes to such life situations. He asks Ritsu why he is telling him this, which Ritsu asks himself as well.
Takano attempts to leave, telling Ritsu to let go of him, which he complies. Ritsu, thinking, tells himself how their relationship happened long ago and they are now boss and employee. He also thinks how, given their situation, it would be for the best. Despite this, Ritsu again clings to Takano, preventing him from walking out of the apartment. Ritsu then tells Takano how An confessed her feelings to him a long time ago and he turned her down - because he was in love with someone else. Ritsu then simply asks Takano not to go to Yokozawa's house. A moment of silence follows.
All of a sudden, Takano shoves him against the wall and slowly begins to kiss him. After laying together on the bed, Takano tells him how he doesn't know what Ritsu's been up to in the past ten years - urging him to tell him everything and not to leave any bit hidden. As Takano begins to embrace him, Ritsu reflects on how much his heart begins to race when he is with Takano and how nobody has ever had such an effect on him. He silently vows to never tell Takano this as they lay together embracing.
