Pavliuchenko/Khodykin made their international debut in late September 2017 at a Junior Grand Prix (JGP) competition in Minsk, Belarus.

They outscored their teammates, Anastasia Poluianova / Dmitry Sopot, by about four points to win the gold medal.

[5] After taking silver at their next JGP assignment, in Gdańsk, Poland, they qualified to the Junior Grand Prix Final.

At the final, held in December in Nagoya, Japan, the pair placed third in the short program, with a fall by Pavliuchenko on the throw jump, and second in the free skate.

They received the bronze medal, finishing third behind Australia's Ekaterina Alexandrovskaya / Harley Windsor and Russia's Apollinariia Panfilova / Dmitry Rylov.

Together with Polina Kostiukovich / Dmitrii Ialin and Anastasia Mishina / Aleksandr Galiamov, they produced a Russian sweep of the pairs' podium.

In mid November they won their second Grand Prix bronze medal of the season at the 2018 Rostelecom Cup with a personal best score of 190.01 points.

They ranked third in the short program and fourth in the free skate and won the bronze medal behind their teammates Evgenia Tarasova / Vladimir Morozov (gold) and Nicole Della Monica / Matteo Guarise (silver).

[6] When Natalya Zabiyako / Alexander Enbert withdrew from the 2019 European Championships, Pavliuchenko/Khodykin were named as their replacements on the Russian team.

In the free skate, Pavliuchenko fell on their throw triple loop, which she attributed to a lack of confidence on her part.

[12] The free skate proved difficult, with Pavliuchenko falling twice, once in their opening transitional moves and once on their throw triple flip, in addition to a smaller error on their twist lift.

[17] This proved to be their final competition for the season, as they had been assigned to compete at the World Championships in Montreal, but these were cancelled as a result of the coronavirus pandemic.

[20] They were scheduled to compete on the Grand Prix, but withdrew after Khodykin contracted an acute respiratory infection.

[26] Pavliuchenko fell on their throw jump in the short program at the Final, resulting in them placing ten points behind Mishina/Galliamov in that segment.

[31] The results qualified them for the Grand Prix Final, to be held in Osaka, but it was subsequently cancelled due to restrictions prompted by the Omicron variant.
