To find love, seven strangers leave Japan and embark on a journey through the African continent.
The new members assemble in Kenya, the first country on their journey; before heading out on safari, Shu-mai learns he shares a birthday with Su-su.
In Kenya, the members visit Kibera, the largest slum on the continent; they stop by the Ainori school, founded in 2005, and meet some of its graduates.
Without his cell phone, U-zi doesn't know how to tell if Kou likes him; to get her to notice him, he does something unusual.
After a tandem bicycle outing, Shu-mai talks to Su-su; while U-zi is still thinking about leaving, the members head to the highlands for a race.
U-zi, who has never asked a girl out before, musters the courage to confess to Kou; the Love Wagon makes its way to Uganda.
Hide gets a chilly reception; Shu-mai tries to talk to Su-su along the White Nile, but she has her eye on someone else.
Haribo's health worsens, worrying Su-su; the members meet Uganda's ugliest man, one of the country's many disabled people.
With help from his friends, Shu-mai gets a makeover; one of the members takes a liking to Hide; the group speaks with former child soldiers.
Hide and the driver take Shu-mai to see a love shaman, who prescribes a magical meal to capture Su-su's affections; Haribo returns to the van.
One couple's blossoming romance shows signs of strain during an overnight camping trip to Lake Victoria; Su-su decides to confess to Haribo.
The Love Wagon rolls on to Rwanda, where new members await, including dance instructor Yuina and ninja buff Joy-kun; ill with typhoid, Kou goes on ahead.
At a rural hospital, the members observe the country's drone delivery system for blood transfusions; they also learn about the Rwandan genocide.
With Kou and Yuina out sick, Husky is the only female member on the love wagon; when she gets sick too, the men try to come up with ways to cheer them up.
Joy-kun asks the staff to have Husky meet him outside. O-ji worries about Kou, who is still very ill, and the members visit Lake Kivu.
O-ji plans a surprise for Kou while camping on an island in Lake Kivu, but a fierce storm stops him; Kou makes an announcement the following morning.
The remaining five members board a plane to Tanzania, where two new members join, including idol cafe proprietor Aonyan and former host club manager Genove.
Husky decides to spend the day with Genove, to Joy-kun's frustration; the members visit the famous archaeological site of Laetoli in Tanzania.
As Genove causes a stir amongst the members, Hide proposes climbing Mount Kilimanjaro, a challenge that ended prematurely for him more than a decade ago.
The members begin their six-day trek to the top of Mount Kilimanjaro; during the ascent, Joy-kun tries to connect with Husky.
On the final leg of the trek, all seven members make their way to the summit of Mount Kilimanjaro, but the extreme conditions take a physical toll.
Husky reflects on her mountain trek and how it's affected her view of Joy-kun; after finishing the climb, Hide tells the group about a big decision.
Aonyan gives Genove her response to his confession; the remaining members move on to Zanzibar, where Husky opens up to Joy-kun about her past.
